Beetle ESP32-C3 RISC-V Core Development Board

This is a microcontroller based on an ESP32-C3 RISC-V 32bit single-core processor. On a 25x20.5mm board, up to 13 IO ports are available so you have enough connections for any project. The Beetle ESP32-C3 supports Wi-Fi and Bluetooth 5.0 (LE). Detailed information about the Wi-Fi function can be found in the documentation. In addition, an expansion board is included. The Beetle ESP32-C3 RISC-V supports a lithium battery, which can be connected directly via the pins on the board. 

The Beetle ESP32-C3 can be programmed using Arduino DIE, ESP-IDF, MicroPython, C, and Python.
