I've finished the design and assembly process and now have two main control boards successfully assembled. The MGC3130 documentation is absolutely chaotic, so finding a single documentation sheet is nearly impossible. Lots of bouncing around between pdf's. Current issue is the MGC3130 has no firmware loaded on it and the only examples I can find are for a PIC32(obviously not the ATMEGA32u4 I have in my build). I'm slowly making my way through the documentation and example C files and recreating the firmware updater example.
