How FTP 2023 will Help India To Achieve Target US$ 300 Bn of Electronics Production by 2026

On 31st March 2023, the New Foreign Trade Policy (FTP), 2023 was released by the Minister of Commerce and Industry, Piyush Goyal, along with the Handbook of Procedures (HBP), 2023. The same has been notified by the Directorate General of Foreign Trade (DGFT) on 1 April 2023. The new policy is of great relevance for the Electronics Systems Design & Manufacturing (ESDM) Industry which contributes to a significant chunk of imports, exports, as well as is a large contributor in E-Commerce. The new FTP 2023 will also enable achieving India’s ambitious export target for the Electronics industry which is over US$ 16 Bn in the current Financial year. This has to be increased exponentially to over US$ 100 Bn if India needs to achieve the ambitious target of US$ 300 Bn of electronics production by 2026. In the policy, various alterations have been made to shift the focus to tax remissions from incentives. It is also looking for greater assistance via automation, technology and constant process re-engineering. Most importantly, the core attention has been given to the emerging regions such as e-commerce exports, developing districts as export hubs etc.

According to the Press Information Bureau, the minister told the media, "The policy is dynamic and has been kept open ended to accommodate the emerging needs of the time. He stated that the policy had been under discussion for a long time and has been formulated after multiple stakeholder consultations. India's overall exports, including services and merchandise exports, has already crossed US$ 750 Billion and is expected to cross US$ 760 Billion this year."

The remarkable achievement in the overall export figure of crossing US$ 760 Billion in these challenging times across the world has been the result of enthusiasm and encouragement pumped in by the Prime Minister. This achievement is in sync with the target set in the roadmap in 2021 after the interaction with the Prime Minister. Every opportunity for export must be captured and utilized effectively. In the next 5 months during India’s G20 presidency there should be a massive concentrated outreach with the world both sector-wise and country-wise,” added Minister Goyal.

How FTP Is Going To Be A Game-changer For India’s Electronics Industry

On four important pillars, the FTP policy is completely relied on viz., incentive to remission, export promotion through collaboration, ease of doing business, and e-initiatives.

According to the industry body ELCINA, the key highlights of the FTP include the following among others:

  • There is no end date to the new policy. Subsequent revision(s) shall be done as and when required.
  • Approvals for various permissions under FTP shall now be online without any physical interface.
  • Reduction in user charges for MSME under Advance Authorization (A) and Export Promotion Capital Goods (EPCG) schemes.
  • Revamp of e-Certificate of Origin (CoO) platform for self-certification of CoOs as well as automatic approval of the same is proposed, where feasible.
  • Paperless filing of export obligation discharge applications for greater use of technology
  • Facilitation of e-commerce export by extending all FTP benefits to such exports.
  • Introduction of a special one-time amnesty scheme for one-time settlement of default in export obligations.
  • With no sunset date, the policy appears to be dynamic with long-term focus ensuring certainty and support to the export industry in India as well as FDIs. Effective implementation of Policy will be key to its success.
  • Automation of processes and paperless filing of applications may aid in ease of doing business objectives of the Government. Businesses will need to adapt their systems to such digitized procedures.
  • A lot of MSME players are an essential part of the Electronic Industry and help in its growth. Reduction in user charges in case of AA and EPCG schemes for MSMEs is likely to reduce the operational cost and encourage further exports by such enterprises.
  • The establishment of E-Commerce Hubs and ONDC (Open Network for Digital Commerce) shall form an essential support system to the Electronics industry to promote its growth. They may also facilitate significant growth in digital cross border trade.

Highlighting the importance of FTP in India’s electronics industry, Sanjay Agarwal, President ELCINA & MD, Globe Capacitors said, “As we are aware that this policy was long awaited and brings about a major shift in India’s approach to foreign trade, simplifying the import procedures and export promotion. With this policy, we hope that India will be able to achieve the ambitious export target of the electronics industry of over 16 million dollars in the current FY and it has to cross 100 billion if we want to have the electronic production of around 300 billion by the end of 2026.

Moreover, Pankaj Jain, who is the director at Ernst & Young (EY) also stated that the FTP 2023 changes the approach from incentive based to tax remission-based model. Obviously, there are no more MEIS/SEIS based schemes. The policy sticks to basic schemes of AA, DFIA, RoSCTL, RoDTEP, EPCG etc. Exports would be promoted through collaboration between exporters, states, and districts. Also, there would be special focus on emerging areas such as e-commerce exports, developing districts as export hubs, streamlining Special Chemicals, Organism, Materials, Equipment and Technologies (SCOMET) policy etc.

Electronics System Design

The Strategies to Lead India’s Electronics System Design

During the period of 2015-2020, when the foriegn trade policy aimed to target exports of USD 900 billion by the end of 2020 and later it was extended for three years until the end of March 2023. Now, the government is looking forward to escalate the nation’s total exports to USD 2 trillion by the end of 2030, with similar contributions from the service sectors as well as merchandise. Alliances with exports and with the guidelines of trust, the FTP is centered on and is looking to formulate seamless automation and re-engineering to craft trouble free trade for the exporters.

Now, in the cross-border business, the government is also aiming to encourage the utilization of the Indian currency, assisted by the new-fangled payment settlement scheme unleashed by the RBI in July 2022. The FTP is promoting development of the electronics industry and export promotion along with wiping out the incentive schemes to a regime which is facilitating based on technology and the proposition of partnerships.

Going Forward, Kartik Kalra, Manager at Ernst & Young (EY) said, "The FTP 2023-28 places significant emphasis on SCOMET policy and aims to streamline the licensing process for the export of dual-use items. The policy aims to consolidate all policies related to the export of dual-use items under SCOMET at one place to simplify the process and make it easier for industry compliance. The policy also aims to make the export of SCOMET items more globally competitive and facilitate the export of dual-use high-quality goods and technology. These initiatives are essential for India to achieve its export targets and remain a competitive player in the global market.

Circuit Diagram - Simple LED VU Meter

The circuit diagram of the LED VU meter is very simple and easy to understand. If you look at the pinout of the. LM3915 is a digital IC that is used to create a visual display of sound volume, often called a VU meter. It works by breaking down an audio signal into 10 equal parts and comparing each part to an internal reference voltage. The chip has 10 output pins, each one corresponding to an LED. The voltage level at each output pin is set using a voltage divider. When an audio signal is fed into the chip, it is first rectified to a DC voltage, and then passed through the resistor network. As the voltage of the audio signal changes, the voltage at each output pin also changes. When the voltage at a particular output pin exceeds the reference voltage, the corresponding LED will light up. This gives a visual representation of the volume of the audio signal. To demonstrate the circuit we have used a simple PAM8403 based audio amplifier and a speaker.

Experts Explain Why J&K’s Recent Lithium Discovery will not be Able to Boost India’s EV Growth Currently

A month back, around 5.9 million tonnes of Lithium have been discovered in the state of Jammu and Kashmir for the first time, claimed by the union government. But, experts on the other hand stated that Lithium reserves were already discovered in the state back in 1999. Lithium, often known as the ‘White Gold’ is now a very important mineral as it is mostly utilized in the manufacturing process of batteries. And because of their higher density they are used in smartphones, electric vehicles, and other electronic devices. India now stands as the sixth biggest known reserves of Lithium resources in the globe. As per the official statement of the central government, out of thee 51 mineral blocks, 5 blocks pertains to gold and other blocks pertains to commodities like potash, molybdenum, base metals etc. spread across 11 states of Jammu & Kashmir (UT), Andhra Pradesh, Chhattisgarh, Gujarat, Jharkhand, Karnataka, Madhya Pradesh, Odisha, Rajasthan, Tamil Nadu and Telangana.

Now, India is undertaking various efforts to boost the growth of the electric vehicle industry and also trying to make it affordable for the people. Some experts and government officials believe that this massive discovery of Lithium will provide impetus to the manufacturing of EV battery cells. In order to uplift the growth of lithium-ion battery manufacturing, India requires Rs 33,750 crore of investment, reports Council on Energy, Environment and Water (CEEW). By the end of 2030, the country’s lithium battery production is anticipated to be around 70-100 GWh. According to automobile experts of the country, the discovery seems very optimistic for the future of the EV industry. In this regard, Sohinder Gill, Director General, SMEV and CEO at Hero Electric told CircuitDigest, "We applaud the government's efforts in finding an Indian lithium resource.  It's a big step forward for the nation. Only a few nations now supply  lithium for the production of batteries. Lithium accounts for ~15% of the battery's cost. The cost of batteries could drop by 5% if we can purchase lithium from the Indian reserve for a price that is 2/3rd of the cost of the imported material, making EVs more affordable. The EV sector will become "Atmanirbhar" and the control of Chinese firms over the raw material will be further diminished if we are able to obtain the lithium in sufficient quantities from Indian deposits."

Since lithium is a major component in batteries, its discovery in J&K will help India progress at a faster pace in the field of battery manufacturing for the automotive industry and consumer electronics. According to a Counterpoint Research survey, the global energy storage demand for just passenger EVs is expected to reach over 3.8TWh by 2030. Along with the demand from CVs and renewable energy storage like solar and wind, the total energy storage demand for 2030 will reach a much higher number. Although other battery chemistries are being developed, as of now lithium batteries are the most reliable for energy storage. China, Europe and the US all are racing to set up battery manufacturing plants. The recently discovered lithium deposits will help India strengthen its position in the global energy market.

Lithium Extraction

India’s Current Lithium Mining Scenario and Possible Challenges

As of 2022, India was importing battery cells for battery pack assembly mostly from China. According to the Ministry of Commerce and Industries, India imported Rs 163 billion worth of lithium and lithium-ion between April and December 2022.  In 2022, India cleared a budget of Rs 18,100 crore to set up 50GWh of ACC manufacturing capacity by 2030 under the PLI scheme. The ACC PLI is expected to boost India’s EV adoption and strengthen India’s position in the energy market as well. EV sales in India are expected to reach 65% of total vehicle sales or over 24.5 million units by 2030. In an exclusive interaction with CircuitDigest, Abhik Mukherjee, Research Analyst at Counterpoint told, "the discovery of lithium along with the 2023 budget announcement of reduced excise duty on machinery required for manufacturing lithium-ion batteries will help India achieve its EV and energy generation targets at a much lower cost. It will reduce import dependency, new battery manufacturing plants will be set up, the mining sector will experience a boom and new job creation will be witnessed.

The Salal-Himalaya region where the deposit has been found is a geographically very delicate region. It is being feared that the earthquake-prone area will face ecological destruction if heavy mining activities are carried out. Moreover, lithium extraction is a water-intensive process. Nearly 2 million liters of water is required to extract just 1 tonne of lithium. This will put huge pressure on the region’s ecosystem. Experts are suggesting ways for sustainable mining, but the higher cost of sustainable mining will reduce revenue and profits. Currently, India does not possess the technology for lithium extraction. “As India allows 100% foreign investment in the mining sector, it is expected that foreign companies will be given the responsibility of lithium extraction initially, which is not favorable for the domestic mining sector. But from a long-term perspective, we expect India to benefit from the technology transfer. Alongside these hardships, the threats from radical groups operating in and around the J&K region are something that the government needs to neutralize before the mining begins,” added Abhik. The project has the potential to face a lot of heat from locals, climate activists and radical groups, and the government will have to work its way around these hardships for a greener future.

The Geological Survey of India (GSI) experts noted that it is the time to view and scrutinize how much of the discovered lithium is viable and feasible and can be commercially extracted. More examination will actually discover the volume of the total reserve. China on the other hand has already unleashed top-notch infrastructure and technological equipment and their years of experience of lithium mining extraction and refinery is an added advantage. India requires more government assistance, investment, and energy. Also, India lacks experience in refining lithium because it is associated with rocks and other minerals. The rocks need to be broken and wiping out certain chemicals with evaporation and also magnetic contamination with magnets. India has no experience in doing all these activities and moreover, there is no trusted technology, machineries and industries associated with this.

Speaking about the grave challenges of extracting Lithium in India, Senior Geologist and Earth Scientist Dr. Sreedhar Ramamurthy told CircuitDigest exclusively, "There is huge euphoria over the reported 5.9 Million Tonnes of "inferred" lithium ore near Salal in J&K based on the preliminary survey by GSI. GSI has earlier reported finds of Lithium in Karnataka, but this has attracted a lot of attention. The actual quantity of Lithium ore and extractable amount would be only known after detailed exploration is undertaken. Generally Lithium content is less than 2% of the ore. The technology to extract Lithium has to be sourced. Being in a fragile ecosystem of the Himalayas, it's also a major concern as to how mining would adversely affect the local environment. It's also worth noting that EVs could be some relief to the polluted urban environments but they fundamentally seem to be yet another 'false-solution' to the larger issue of climate justice."

Although the discovered Lithium is likely to uplift the growth of EVs in India, experts have clearly stated that if the resource is not mined scientifically then there could be serious environmental depletion and it could pose serious risks of soil degradation and air pollution. On the other hand, the waste disposal, refining, and open cast mining contaminates the groundwater largely thereby disturbing the biodiversity. The extraction from the ore is mostly water-intensive, around 2.2 million liters of water will be wasted for extracting one tonne of lithium. Additionally, mining in the Himalayan region has various societal impacts and could displace the local communities, explain experts. This particular region is home to a huge number of indigenous communities and the government could face fierce activism over this issue if mining begins.

Lithium Refining

Conclusion and Possible Solution

Back in May 2021, the central government announced a PLI scheme of Rs 18,100 crore for a term of five years to manufacture Advance Chemistry Cells (ACC) in the nation. In the same year in June, there were three bidders such as Reliance New Energy Limited who signed the agreement under the PLI scheme. Most importantly, as there are no possible alternatives, the country will have to carry on importing because there are deadlines for various ventures aimed at zero-carbon emissions coming near. Also, during the 26th United Nations Climate Change Conference of the Parties (COP26) in Glasgow in 2021, India assured to reduce emissions to net-zero by the end of 2070 and therefore, the discovery of lithium would be critical to meet the targets in the coming years.

According to a report by the International Energy Agency (IEA), there could be lithium shortages internationally towards the end of 2025 and by 2050 around 2 billion electric vehicles are required to meet the net-zero target. But, EV's sales reached only 6.6 million globally. The supply of lithium is facing hurdles not only from the augmenting demand, but the resources are concentrated in few places and most of its production is available in regions with vast water stress.

Speaking of the growth and possible solution, Rajoo Goel, Secretary General of industry body ELCINA said, “Discovery of Lithium reserves in J&K is a very significant and positive development for India. It is an invaluable resource and will strengthen and accelerate the development of EV's and renewable energy capacity in India. It will enhance energy storage capacity and reduce use of fossil fuels. The key to success of course lies in successfully mining and processing Lithium for industrial use. Lithium ion batteries are a key component for energizing electronic equipment and transportation systems. We however, need to ensure safe use and recycling of Lithium based products to protect the environment.

The History of Arduino Part 2: Revolutionizing Embedded Electronics

Submitted by Staff on

Shields Up! New Boards Incoming!

It is arguable that a significant contributing factor to the success of Arduino, especially in its earliest days, was the cottage industry of complementary boards created and sold by third parties. These boards, known as shields, could be inserted into the unique headers of the Arduino form factor found onboard the Diecimila, Duemilanove, and current generation Uno boards. They helped to expand the functionality of the underlying Arduino board by allowing designers to quickly integrate a variety of sensors and actuators into their Arduino-based projects. The interoperability and the ability to nest multiple shields proved a decisive victory for Arduino. Indeed, today many other embedded system manufacturers offer development boards that feature compatibility with Arduino shields (Figure 1).

Arduino Shield

The popularity of the original Arduino form factor did not prevent the company from introducing a variety of additional form factors that retained the ease of tinkering and programming. The electronics at the heart of the Arduino board have evolved over the years. Newer microcontrollers have been incorporated to provide more processing horsepower. Over the years, hardware has been added to provide increased functionality, such as Wi-Fi® and BLUETOOTH® wireless communications. Arduino has even released technology and curriculum bundles aimed at teaching science and robotics courses. Some of the highlights from the years of hardware evolution are:

  1. Mega: Physically a much larger board than the Uno that exposed significantly more I/O pins (the current revision has 54 digital I/O pins, 16 analog inputs, and 4 UARTs) to give the designer more flexibility and to create more complex systems (Figure 2).
Arduino Mega
Figure 2: The Arduino Mega. (Source: Mouser Electronics)
  1. Micro and Nano: As their names imply, Micro and Nano form factors are much smaller than the Uno form factor. The smaller form factor made them preferable for final designs or applications with significant size restraints.
  2. Lilypad: Explicitly created for those with an interest in wearable electronics. Conductive thread replaces traditional wire as the means of connecting components.
  3. MKR: The MKR line of boards is arguably the first attempt of Arduino to bridge the maker and professional markets. While the MKR family shares a compact common form factor, it offers a wide variety of architectures, communications protocols, shield-based sensors, actuators, and system interfaces. For example, there are MKR boards with Wi-Fi, LoRa, and GSM wireless protocols. In addition, there are shields for interacting with DC motors, CANbus, and RS–485 industrial protocols.
Arduino MKR
Figure 3: An example of the Arduino MKR form factor. (Source: Mouser Electronics)
  1. VIDOR 4000: The VIDOR was Arduino’s first attempt at Field Programmable Gate Array (FPGA) hardware versus microcontrollers. While the VIDOR shared the same Cortex-M0 32-bit SAMD21 as other MKR boards and was thus programmable via the Arduino IDE, the FPGA-side of the board never really fulfilled the promise of bringing hardware description languages (HDL) such as Verilog and VHDL to the masses. Though using industrial-strength tools, it is possible to program the VIDOR with HDL; it has never proven to be something that most makers (or even professionals) have really tried to attempt.
  2. Portenta: The Portena line of embedded system products marked Arduino’s expansion into hardware for dedicated professional development. Portenta brings numerous hardware improvements that make it preferable for industrial applications such as factories and automobiles. In addition, built-in support for wireless protocols such as Wi-Fi, BLE, LoRa, LTE Cat-M, and NB-IoT and legacy wired protocols such as RS-485 means Arduino can help bridge the gap between the old and the new, ensuring reliability while also adding new functionality such as machine learning and digital twins. Furthermore, the seeds of Arduino’s investment in the education market will sow countless rewards as young people who learned about electronics using an Arduino Uno will have less of a learning curve with the newer professional-grade Arduino products.
  3. Nicla: The Nicla also falls under the professional umbrella, with the Nicla Vision focusing on AI-based computer vision applications (Figure 4). The almost stamp-sized form factor with the built-in camera means the Nicla Vision can be easily integrated into existing machinery with minimum fuss. The Nicla Sense ME has the same form factor while providing professional-grade motion and environmental sensing capability.

In the late 2010s, Arduino made moves to expand from just a hardware manufacturer to a full-fledged embedded systems ecosystem. 2019 saw the release of an online test-based certification program that allowed individuals to prove their knowledge of basic electronics, software development, and certain aspects of the Arduino ecosystem. Then in September 2020, Arduino took ownership of Google’s Science Journal smartphone application used in many science curricula (Figure 5). They even expanded the app's capability to use not just the onboard smartphone sensors but also sensors found aboard the Arduino Nano 33 BLE Sense development board.

Arduino Today, Arduino Tomorrow

As we find ourselves rapidly approaching the beginning of Arduinos third decade, it is pretty remarkable to look back at the growth of an ecosystem that has already revolutionized electronics education and is well-positioned to do much more in the future. Today Arduino is much more than an artist-designed 8-bit microcontroller-based circuit board and barebones software development environment. Indeed, they are keeping pace, if not leading the charge, in moving embedded systems technology into the future.

There are two major trends that embedded systems developers must continue to appreciate and invest in if they wish to remain competitive. The first is the push of AI technology (such as machine learning) to the “edge,” meaning embedded electronics right at the point of action, far removed from relying on high-end servers to do all the computationally intensive processing. The Portenta and Nicla products mentioned earlier, along with partnerships with companies such as Edge Impulse, show that Arduino has no intention of resting on its laurels and is embracing AI technology.

The second trend is the continuing incremental rollout of the Internet of Things and the recent emergence of technologies explicitly built for IoT, such as Thread. In recent years, Arduino embraced the cloud and IoT (Figure 6). Starting as Arudino Create before being rebranded as Arduino Cloud in 2021, the hosted service gives developers a convenient cloud-based platform to remotely monitor and control Arduino-based solutions. Arduino made this even more convenient with the release of their IoT Remote smartphone applications available for both iOS and Android.

The future is looking bright for Arduino. In the course of researching and writing this article, additional significant announcements were made regarding future Arduino hardware and services. First, the company just announced Opta, their first-ever Programmable Logic Controller (PLC) for industrial applications (Figure 7). The Opta will be programmable using industry-standard ladder logic diagrams and function block diagrams. Additionally, the company announced Arduino Cloud for Business. In a way that mirrors how the Pro line of products moved Arduino into industrial-grade hardware, Arduino Cloud for Business will transform Arduino Cloud in a similar manner. In addition, the business offering will include features that will make Arduino-based edge devices easier to securely provision, monitor, and update at scale.

Happy 20th Birthday, Arduino!

2023 marks Arduino’s 20th year of existence. So much has changed in our world in the intervening years. Then, there were no iPhones or Android devices, Netflix was a company that sent you DVDs via snail mail, and embedded systems were the purview of large corporations and the most tenacious hobbyists. Today we live in a world where almost anyone interested in electronics can get involved in a very hands-on way. And while Arduino is not the only company to help create this modern world, it certainly casts a big shadow for a small company started by five people at a small academic institution in Ivrea, Italy. So here is to the next twenty years, Arduino.

A Simple DIY Wireless Switch using 433Mhz RF Module

When it comes to giving your projects wireless capabilities, A 433MHz RF Module is the most common and easiest way to get things done. A 433MHz RF module uses the ASK modulation methods to transmit and receive data between two devices. It is widely used in many applications, including remote control systems, wireless security systems, and telemetry systems. So in this tutorial, we will make a simple circuit with the help of the 433 Mhz RF module that requires no microcontroller and no code to light an LED wireless. 

Note: If we search the web for 433MHz RF modules, you will find many different variations of this module, but only the green module with variable capacitor works, at least from what we have tested. 

433Mhz RF Module Pinout

433Mhz RF Transmitter

DATA Pin accepts digital data that's needed to be transmitted.

VCC is the power pin of the module. The operating voltage of the device is 3.3V to 5V. Please note that the range of the device is directly proportional to the supply voltage. This means providing more voltage can provide it with more range.

GND is the Ground pin of the RF Transmitter module.

433Mhz RF Receiver

VCC Provides power to the 433MHz module. Unlike the transmitter, the receiver requires a 3.3V - 5V supply voltage.

DATA There are two data pins for the module This is the data out pin of the module.

GND The first ground pin of the module.

Circuit Diagram of 433MHz RF Transceiver

The schematic diagram of the RF link is shown below, the circuit is very simple and can be built very easily.

The History of Arduino Part 1: Introducing Arduino

Submitted by Staff on

The Italian Renaissance was an incredible two-hundred-year period of human history marked by remarkable advancement in both the arts as well as science and technology. Names like Leonardo da Vinci, Galileo Galilei, and Sandro Botticelli are but a few of the great minds that gifted the world with incredible knowledge, art, and inventions (Figure 1). A few centuries later, a renaissance in electronics would emerge from a small town in Italy named Ivrea. And it all began with a hand-soldered circuit board that would become known globally as Arduino.

In the (Academic) Beginning…

Before the early 2000s, many engineers and makers interested in embedded electronics cut their teeth on the PIC-based BASIC Stamp platform. BASIC Stamp became popular since the hardware was relatively inexpensive compared to most microcontroller platforms of the time. $139USD (inflation-adjusted to 2022, almost $400) in the 1990s got you a Stamp, parallel port programming cable, and a copy of Stamp Editor. The BASIC-esque programming language (a variant named PBASIC) was easy to learn, but the editor only ran on Windows. Still, the emphasis of BASIC Stamp was on those with a technical mindset. For many of those with an artistic bent who yearned for a way to integrate technology into their art, the BASIC Stamp proved to be less than ideal as it was not programmable on a Mac, and the cost was still a bit high, especially for students.

Around 2003 this would begin to change. Enter the Interaction Design Institute Ivrea (IDII) and a perfect storm of technology and art (Figure 2).

A group of students and professors whose work revolved around interactive art were frustrated that the technology of the time was more a hindrance than a help in bringing their creative works to life. Some of the earliest people involved were Hernando Barragán, Massimo Banzi, Casey Reas, and Ben Fry. Barragán’s master's thesis was the Wiring development platform built around the humble ATmega128 microcontroller and a handmade circuit board. Banzi was one of Barragán’s advisors along with Reas. Fry and Reas were the creators of the processing integrated development environment (IDE). Hernando would leverage processing as the basis for the original Arduino IDE, which was replaced only recently (September 2022) by the more modern Arduino IDE 2.0. These decisions would lay the foundations for the beginning of the worldwide Arduino ecosystem.

NOTE: It should be noted that since the initial IDE launch, Arduino has also released a command line interface (CLI) and a text-based linter that is useful for those seeking modern professional development tools.

Going Commercial and Open Source

The first commercially available board was the Arduino RS232 featuring through-hole components, a DB-9 serial port, and a DC barrel jack power supply (Figure 3). This design made it easy to hand-solder and reproduce in decent quantities. The simple design, coupled with the decision to release the hardware design under a Creative Commons license (specifically a CC BY-SA license), propelled Arduino into the hearts and minds of countless artists and electronics hobbyists.

Low cost was another consideration, as the Arduino was initially targeted at art and design college students. The decision to release the hardware and software (the IDE is released under a GNU general public license, version 2) is arguably one of the defining and, at the time, riskiest propositions for the then-fledgling electronics ecosystem. The pending closure of IDII in 2006 and its academic program being subsumed into the Domus Academy in Milan also helped prompt the founders to adopt an open-source model for Arduino.

In 2008, the five founding members of the Arduino project formed Arduino LLC to handle the intellectual property of the Arduino. It was initially envisioned that other companies would manufacture and sell the “official” Arduino boards while Arduino LLC would receive royalties from these sales. Of course, due to the open-source nature of the Arduino platform could take the design files and create both exact duplicates or improved boards (Figure 4). The only stipulation being they could not be named “Arduino” as that name was trademarked exclusively for boards licensed by Arduino LLC. Surprisingly while many derivative boards did find their way to the market, they did not have a significant negative impact on official board sales. Customers did indeed reward Arduino LLC with loyalty, recognizing the superior quality of the hardware and the effort Arduino LLC put into expanding the hardware platform and constantly improving the software development tools. Additionally, the form factor of the original Arduino boards has been faithfully maintained throughout the lineage of the credit card-sized Arduino boards, including the Diecimila, Duemilanove, and the current Uno R3.

It was not always smooth sailing for the Arduino LLC team. In the 2010s, a legal dispute erupted amongst the founders. Without rehashing this dark period, the bottom line was that the trademark Arduino was only good for boards sold in the United States. A company (Arduino SRL) run by one of the founders, Gianluca Martino, held the Arduino trademark in Italy. In response, Arduino began to market Arduino boards outside the United States as Genuino. For a few years, there was quite a bit of confusion in the Arduino ecosystem regarding which boards were compatible with which companies' development software. In 2017, the other four founders regained the trademarks held by Arduino SRL, and once again, Arduino was made whole.
