This little board allows you to safely shutdown your Raspberry Pi project when using either Helder’s RetroPSU or Adafruit’s PowerBoost 1000c to power it. This board also works great with Bluup’s OneForAll software. Comes fully populated and ready to go.
- GND: Ground
- EN: RetroPSU / PowerBoost Engage Pin
- PO: GPIO PowerOff
- SD: GPIO ShutDown
Add the following two lines to your /boot/config.txt*:
dtoverlay=gpio-poweroff,gpiopin=[PO: replace with GPIO],active_low=1
dtoverlay=gpio-shutdown,gpio_pin=[SD: replace with GPIO],active_low=1
*If you’re using Bluup’s OneForAll scripts or other scripts that handle the shutdown pin, don’t add the shutdown line.
