Motor Control Board

This board is for two DC motors (5-40V) in combination with an Arduino. You can control each speed with one PWM and each direction with 2 digital ports.
- Forward: ON - OFF
- Stop: OFF - OFF
- Backward: OFF - ON
Two control LEDs indicates the PWM. And the other four indicates the direction of the motors.
With the jumper one can power the output with an external power supply or - for testing purposes only - via the arduino.
