Small PCB (49mm x 34mm) with all through-hole components. It drives four motors using two FRM050's and two L293D's. Motors connect to the green terminals, motor power connects to one blue terminal and logic power connects to the other. The pin header provides an alternate way for connecting logic power and two sets of four pins for control of the two pairs of motors. It also provides a way to plug the whole board into a solderless breadboard quite easily.
