PWM power inverter printed circuit board for controlling the direction of travel and speed of a large DC motor up to 20A (depends on the relays which mount). The recirculation diode is onboard.
Two LEDs indicate the direction of rotation and a third LED illuminates the control.
The circuit can operate autonomously, adding the potentiometer for speed control and buttons / switches for the direction of travel, or it can be connected to an embedded Micro-GT or Arduino system or even to a common PLC.
