Good news everyone! I received the boards from OSH park! I soldered on some components and tested the ATMEGA 328P-AU. I currently am running a blink at 1Hz using Atmel Studio. Seriously considering adding debug wire...

I have found the following design problems:

• Serial Clock for the 328p is abreviated SCK not SCL - I assigned it to the incorrect pin.
• 328p Pin 1 marker not visible on silkscreen.
• Outline is not symmetrical.
• Trace from Pin 1 to Left H-Bridge crooked.
