This shield allows you to use a computer power supply (or other power source) to use your Arduino to switch high current. With RFP30N06LE MOSFETS, you can easily control a lot of current directly from your Arduino.
The board provides six PWM outputs via screw terminals. Check the datasheet for the MOSFET below for full specifications on how much current this board can handle. This board is a very easy way to start using MOSFETS for your next high current project.
A protection diode has been added to the power input of this version of the board.
Note: If you want to stack another shield on top of this one, you will want to double-up on the stackable headers to clear the MOSFETs.
