Features:

Using original IRF520 Power MOS, you can adjust the output PWM.
Arduino drive up to 24V allows the load, such as LED lights, DC motors, miniature pumps, solenoid valves.
PWM dimming LED can be used to achieve stepless dimming, variable speed motor.
Note: Above 1 A load, you need to install heat sink.
