Product Introduction


Beetle ESP32 - C3 (RISC-V Core Development Board)


On a coin-size board of 25*20.5 mm, there are up to 13 IO ports broken out, so you don't have to worry about running out of IO ports when making projects. Meanwhile, the li-ion battery charging management function is integrated on the board which allows for directly connecting the li-ion battery without extra modules, while ensuring the application size and safety.


The equipped expansion board for Beetle ESP32-C3 brings out more power sources without increasing product volume, more convenient for solder. Besides, the onboard easy-to-connect GDI saves the trouble of wiring when using a screen.


Beetle ESP32-C3 supports WiFi and Bluetooth 5 (LE) dual-mode communication that reduces the difficulty of networking, and also both Bluetooth Mesh protocol and Espressif WiFi Mesh are supported for more stable communication and a larger coverage area.


Detailed tutorials for Beetle ESP32-C3 are provided for users to use the controller’s WiFi function, such as connecting to IoT platforms like Aliyun, IFTTT, etc. Or users can use various sensors and actuators from DFRobot to build up IoT systems.


Beetle ESP32-C3 can be programmed by Arduino IDE, ESP-IDF, MicroPython, C, and Python are both supported.
