Here is a simple extension board for the IRF520 Mosfet. Easy connection to your Arduino or another 3-5v microcontroller. Pulse current via a PWM pin and use this to control a pump, LED or other DC device up to 24 V,
This small module is a breakout board for the IFR520 MOSFET transistor. The module is designed to switch heavy DC loads from a single digital pin of your microcontroller. The main goal is to provide an inexpensive way to control a DC motor for robotics applications, but the module can be used to control most high current DC loads. Screw connections are available to communicate with.
