Moitessier HAT and PiCAN-M HAT together?

[flightlead404]

I'd like to have the functionality of both of these HATs

Moitessier HAT 2

PiCAN-M


I can't tell if the PICAN-M has a stacking connector or if these two HATs can be used at the same time.

Anybody know?

PiCAN-M has a pass-through socket for use with a push-through header. So yes, the Moitessier HAT can be stacked on top of it.

Both devices use GPIO22 on the Pi. On the PiCAN it looks like it only drives an LED, but you’d have to deal with software for both devices trying to drive the same pin.

The header pin usage diagram in the Moitessier documentation is how it ought to be presented:

For the PiCAN you have to follow the schematic.

I’d also want to look at the power needs of the two HATs.
