{"NAME":"ESP-C3-01M-Kit","GPIO":[1,1,1,416,417,418,1,1,1,1,1,0,0,0,0,0,0,0,420,419,1,1],"FLAG":0,"BASE":1}

This is a weird development board. Its form factor is one breadboard row wider than a standard D1 Mini. Five of the GPIO’s are used by an RGB, a cool white and a warm white LED.

The template is configured with the cool white LED being LedLink and the warm white one as the power LED.

Board comes with headers soldered in as in the image making its difficult to use with a breadboard.

Flashing

Flash using Tasmota Web Installer and select Tasmota ESP32-C3 option.

For esptool.py download f.e. tasmota32c3.factory.bin and run esptool.py write_flash 0x0 tasmota32c3.factory.bin

To put ESP32-C3 in flash mode GPIO8 needs to be pulled high and GPIO9 pulled low. Some devices have that by default.
