CRITR/pcb gen2

Below is our PCB design for the second generation of CRITR. This generation utilizes an Odroid as the processing unit, instead of the Raspberry Pi. We needed to make the switch-over, because the Raspberry Pi didn't provide as much processing power as the Odroid did. The differences between this generation and the previous included the addition of on-board logic level shifters, pins for the direct connection of the OpenCM, pins to connect a barrel power supplier for the odroid, and a pin for the battery to directly connect.
