Configuration for ESP32-C3
{"NAME":"AI Thinker ESP-C3-12F","GPIO":[1,1,1,416,417,418,1,1,0,32,1,0,0,0,0,0,0,0,420,419,1,1],"FLAG":0,"BASE":1}

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.
