A very tiny board with could be used to control DC motors and Stepper motors. (Two layers)
I used a L293D as heart of this controller - 2 dc motor or a stepper motor 4pins.
Basically, input pins in the left to the board corresponds to pins in arduino o whatever microcontroller, In the right to motor pins.
