I’m starting to work on the Raspberry Pi PCIe adapter for the Pt and wanted to get some feedback on the form factor people would like to see.
My initial thought is to make it large enough to be bolted to the Pi like a standard “hat” with a cutout to keep the Pi’s 0.1” pins exposed. The downside with this is that the board wouldn’t be very stackable making the Alchitry pins hard to access. I guess the standoffs used to attach it to the Pi could be extra tall but that might require different ribbon cables for the PCIe connection.
It could also be designed to just be the same footprint as the Pt and sit beside the Pi. The extra IO on the Pt could then easily run to bottom side connectors. The ribbon cable could run out the right side to connect to the left side of the Pi.
Thoughts?
