{"NAME":"ESP32-S3-DevKitM-1","GPIO":[1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1376],"FLAG":0,"BASE":1}

An entry-level development board from Espressif with all of the ESP32-S3 GPIOs broken out for prototyping as well as CP1202N USB-Serial chip for debugging via a dedicated micro-USB port.

When the board is booted into debug by holding BOOT and pressing the RESET button the USB-Serial chip on the “UART” 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.
