This is an ESP32 XIAO compatible PCB that lets the user control smart home devices with software like esphome, tasmota, or even custom arduino code. The 6 buttons are setup with Deep sleep compatible GPIO pins and two transistors control power flow to an RGB and a voltage divider to measure battery levels.
