GPIO current & voltage specs

Hello, I’m thinking of getting a AutoPi for a project and wanted to first check if someone knows what the current & voltage specs of the GPIO pins are? given that the connections mostly uses 12v, would I need to get some extra relays / transistors to interact with 12v from the GPIO? is it 5v?

Hi @Yered

Welcome to the forum :slight_smile:

The current and voltage specs, follows that of the Raspberry Pi Zero.

I’ve just made this guide for the pinout. I think this is what you are looking for.


Thank you, that’s exactly what I needed!

Hi Yered,

Did you manage to signal the autopi with external sensors?

If so, use it possible to wake up autopi when a sensor is activated?
