Description: 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 6 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.

I purchased these shield to change the direction of the switch tracks (also called turnouts) of my HO trains under DCC control using an Arduino as a DCC decoder. Instead of a PC supply, I used a 20 volt DC laptop supply. Since 20 volts is a bit high for the input to the Ardunio, I replaced the diode with a 12 volt voltage regulator. Everything works great. I finally have full control over my switches via DCC. Each shield controls three switches.
