Espressif has released an upgraded version of its ESP32-C2 v2.0 (ESP8684) chip with improvements in memory, storage and overall performance. When paired with the upgraded ESP-IDF framework, the chip now provides an extra 20 KB of SRAM and approximately 100 KB of flash storage depending on the application. These enhancements are designed to support more complex and efficient IoT project development without adding unnecessary complexity.
The upgraded chip was demonstrated through practical examples such as ESP-NOW, ESP RainMaker and the Matter protocol. In the demonstration, a dual LCD display board based on ESP32-C2 was shown to operate with each screen controlled independently and also simultaneously. In addition, an 8x8 matrix display driven by the ESP32-C2 highlighted its ability to manage data transmission between devices using ESP-NOW, proving the chip’s capacity to handle multiple communication protocols.
In another demonstration, using this new version with ESP RainMaker, it enables smartphone-based control of devices like LEDs. It was also explained that the chip supports the Matter protocol to ensure smooth integration with ecosystems including HomeKit, Alexa, Google Home and Samsung SmartThings. This release is positioned to support complex protocols and multi-device configurations, meeting the demands of advanced connected device applications and unlocking new possibilities for developers.
