Configuration for ESP32

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

Peripherals

  • WS2812B Neopixel
    • On GPIO5 with power on GPIO8.
    • Provided template configures this as WS2812 with GPIO8 as Output Hi for power.
  • 1x front panel user button
    • On GPIO0 (doubles as BOOT0 button)
    • Provided template configures this as Button 1.
  • STEMMA-QT JST-SH I2C bus connector
    • On GPIO19 (SCL) and GPIO22 (SDA), bus shared with onboard sensors.
    • Provided template configures this as I2C 1.

GPIO Pin Mapping

The user pins labelled on the board are set up as User pins in the template, allowing module configuration. This is a quick reference to map the pin label on the board to the module user pin.
