Configuration for ESP32-S3

{"NAME":"ESP32-S3 Feather","GPIO":[0,0,0,640,608,1,1,3840,1,1,1,1,1,1,1,1,1,1,1,0,0,3840,1376,0,1,1,1,1,1,0,0,0,0,0,0,0,0,0],"FLAG":0,"BASE":1}

A Feather form factor ESP32-S3 dev board with 1S LiPo battery monitoring.

This board uses an ESP32-S3-MINI-1-P1N8 module with 8MB of flash and no PSRAM.

When the board is booted into debug by holding BOOT and pressing the RESET button the USB-Serial chip on the USB port exposes a serial connection. This can be used to easily flash new firmware.

Flashing

Flash using Tasmota Web Installer and select Tasmota ESP32-S3 option.

For esptool.py download f.e. tasmota32s3.factory.bin and run esptool.py write_flash 0x0 tasmota32s3.factory.bin

To put ESP32-S3 in flash mode GPIO0 needs to be pulled low.
