{"NAME":"S2 Mini v1.0.0","GPIO":[32,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,0,0,0,1,1,1,1,1,1,1,1,1,0,0,0,0,0,0],"FLAG":0,"BASE":1}

An ESP32-S2 dev board in D1 mini form factor.

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-S2 option.

For esptool.py download f.e. tasmota32c3.factory.bin and run esptool.py write_flash 0x0 tasmota32c3.factory.bin

To put ESP32-S2 in flash mode GPIO0 needs to be pulled low.

Use Zadig to install WinUSB drivers to be able to flash S2 mini.
