Versions of this development board without the red antenna are faulty and should be avoided.

Template maps the IO18 and IO19 as I2C to use with the Grove connector.

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.
