Raspberry Pi GPIO Safe Shutdown and Wakeup Solution

Overview

This project provides a simple and reliable way to safely turn your Raspberry Pi on and off using GPIO pins and the run/reset pad at the backsite, preventing data corruption and ensuring safe operation. It's compatible with any Raspberry Pi model, including the Raspberry Pi Zero 2W.

Safe Shutdown Schematic

Key Features

  • Safe shutdown using GPIO pins.
  • Optional LED indicator for power status.
  • Prevents data loss and system corruption.
  • Works with any GPIO pins on the Raspberry Pi.

Installation

Follow these steps to modify the config.txt for safe shutdown:

  1. Open the config.txt file located in /boot/.
  2. Add the following lines: 
    gpio=27=op,dl
dtoverlay=gpio-shutdown,gpio_pin=17,active_low="y"

From the command line:

sudo sh -c 'echo "gpio=27=op,dl" >> /boot/firmware/config.txt'
sudo sh -c 'echo "dtoverlay=gpio-shutdown,gpio_pin=17,active_low=\"y\"" >> /boot/firmware/config.txt'
