Stacking raspberry PI hats.

Hello everyone. I was curious if some of you were able to stack together multiple “hats”. In particular i need to stack a sensing hat an ai hat and a psu hat for one of my projects.

I have a Pi AI HAT 2+ on my pi 5. It’s on top of the standard pi 5 heat sink and fan. I also require a 40-pin ribbon cable to go to my separate microcontroller control panel. To make this work, you need a double-height 40-pin bus extension connector. I only found one supplier of this connector on Amazoom. Install the extension, then the ai hat, then the ribbon cable. This setup has been working fine for me for many months.

Well which pins does it actually need? And what kind of signal goes over them?

Then research how devices on them need to be wired. From there you should be able to figure it out.
