I should've created this Hackaday project page a long time ago...lots of progress has been made in the 1.5 months of working on this so far. The latest update is that the PCB schematics are complete and reviewed (thanks, Jimmy!) and the components have generally been placed in good spots on the PCB. Check out the 3D screenshot from our CircuitMaker project below!:
Let's hope it's not a pain to route it on a 2-layer board. Fingers crossed!
