Simple SMC 1.1
 Status: Waiting for prototype PCB boards...

This is a simplified version of Chubb's SMC board, but built around a MosFET driver chip that doesn't need the plethora of external parts that the CMRI board does. The board uses a RJ12/6 connector to provide Power (5v or 12v), Ground, direction control and normal, diverging and occupation feedback. It also has a provision for supplying 5v thru the RJ connector and 12V via an onboard DC jack, in case the 5v from the I/O board provides insufficient drive for the tortoise.
