Requires a special ESP32-C3 tasmota32 binary. Download unofficial development build for 4Mb flash or 2Mb flash.

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 using Tasmota32c3 4M Flash option.

If using esptool.py download required files and tasmota32c3.bin and put them in the same folder.

esptool.py --chip esp32c3 --baud 460800 --before default_reset --after hard_reset write_flash -z --flash_mode dout --flash_freq 40m --flash_size detect 0x0000 bootloader_dout_40m.bin 0x8000 partitions.bin 0xe000 boot_app0.bin 0x10000 tasmota32c3.bin
