Thanks, that's very helpful.? I have a pi hat and Pi Zero 2 W and have literally been trying to figure out which way is up and how to plug the Pi into the hat and make sure all the other pins exit in the right direction(s). I can see your stack at 0:54 and I guess it answers my questions.
Next I'll need to attempt to load sBITX software onto the Pi and learn how to modify it to initially work with an HDMI monitor and USB keyboard since I don't have the display used int he sBITX design.? My eventual goal would be to build something like the zBITX presented at FDIM.
