An IoT-focused ESP32-S2 dev board with a display, a variety of on-board peripherals, and standard GPIO/I2C connectors for rapid experimentation and development.

This board uses an ESP32-S2-WROVER module with 4 MB flash and 2 MB PSRAM.

When the board is booted into debug by holding BOOT (on the back) and pressing the RESET button (on the front) 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 i.e. tasmota32s2.factory.bin and run esptool.py write_flash 0x0 tasmota32s2.factory.bin

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

Debug Console Output

The ESP32-S2 serial debug console is available on two test pads on the back of the board, in a cluster of three test pads to the left of the ESP32-S2 module. The TX signal is on the top-left pad with RX on the top-right pad.
