STM on off controller LiPo adafruit power ui

This project was created on 07/10/2024 and last updated 2 years ago.

Description

This breakout is based on the STM326601 on/off controller which allows for the use of a single button to power and control any project. This keeps the UI simplistic saves space.

The first button press will wake up the controller and enable a 3.3V output. Any button presses after that will trigger an interrupt signal and a long button press will disable the 3.3V output and put the controller back to sleep.

This breakout can handle all your power needs with a 500mA 3.3V output, standard JST battery connector, 100mA single cell battery charger and battery level indication.
