This little module is a breakout board for the ER-ACR03075M MOSFET transistor (Metal Oxide Semiconductor Field-effect Transistor), a module can adjust the output PWM. The module is designed to switch heavy DC loads from a single digital pin of your microcontroller. Its main purpose is to provide a low-cost way to drive a DC motor for robotics applications, but the module can be used to control most high current DC loads. Screw terminals are provided to interface to your load and external power source. A LED indicator provides a visual indication of when your load is being switched.
LED lights dimmer, variable speed for DC motors, miniature pumps, solenoid valves
