Raspberry Pi 5 GPIO - Is it the same?

cstanton

It's kinda the same, but different.

I'm still waiting to get a hold of a Raspberry Pi 5 myself, we have one shared internally at the moment and that's being passed around to be able to confirm some details!

I've put up a first draft of the Pi 5 Pinout graphic:  Raspberry Pi 5 Pinouts including GPIO for the 40 Pin Header 

I'm expecting some changes/improvements to the diagram - but not a great deal! Mainly some of the naming, as the RP1 ( RP1 Datasheet - Peripheral Controller Datasheet Draft ) chip now handles the pinmuxing and GPIO, and has GPIO of its own. 

I believe the RP1 dedicates 0-27 of its GPIO to the 40-pin block on the Pi 5 to be used, changed, etc.

There are also new headers on the board, for composite video to the fan and real-time clock battery.

Fortunately, it looks like the majority of your HATs will still be pin compatible!

    I had this problem with Pi code transitioning from Pi 3 to Pi 4. Some apps use low-level interfaces, and broke in that transition. 

    For a LoRaWAN plug-on module, it claimed Pi 3 and Pi 4 compatibility but actually only worked on Pi 3 (which wasn't an issue since the throughput is so low, the Pi 3 was more than adequate).
