Microcontrollers
All microcontroller should have a CAN controller built in.
TBD: How many IOs do we need?

Mezzanine (Board-to-board)
Mezzanine connectors are used to connect controller boards to their carrier boards. When selecting final connectors, please be wary of stack height.

Off-board (Wire-to-board)
Off-board connectors should be able to handle up to 2~3A at 12V. These will be the standard connectors for anything off-board.
