{"NAME":"M5Stamp C3U","GPIO":[1,1,1376,1,1,1,1,1,1,32,1,0,0,0,0,0,0,0,1,1,1,1],"FLAG":0,"BASE":1}BLAKADDER17 when buying from shop.m5stack.com store for a 5% discount.
The C3U uses the ESP32-C3’s built-in USB Serial for program download.
Enter flash mode: Long press on the center button of the M5Stamp C3U when the power is off (G9)
Light controls are for the built-in SK6812 RGB LED.
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.
