An ESP32 Pico dev board in the tiny (22mm x 17.9mm) Seeduino XIAO form factor.

This board uses an ESP32 Pico V3 02 chip with two cores, 8 MB of flash and 2 MB of PSRAM.

The board also includes a CP2102N USB-Serial chip on the USB port for easy device flashing and debug console output access.

Flashing

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.

For flashing via tasmota32.factory.bin, download the tasmota32.factory.bin file.

esptool.py --chip esp32 --baud 115200 --before default_reset --after hard_reset write_flash --erase-all -z 0x0 tasmota32.factory.bin
