This PCB supports 4 LM7805 to power 4 servos. There are 4 holes for PWM entries.

This PCB is made to drive servos from an arduino board. You just have to solder : -six headers : two for power input and ground and four for PWM input. -four LM7805 for power up to 2A per motor, and for less heat in general. -four 100µF capacitors between the regulator's output and ground -four 330µF between the regulator's input and ground.
