Description

3-Channel general purpose NFET driver

This was originally designed to drive an industrial Red/Yellow/Green LED signal light tower from an Arduino Nano, but this can be used to drive any load at up to 60V/500mA, such as RGB LED strips, etc. Connect the positive terminals of your load to your supply voltage and the negative terminals to the _OUT pads of this PCB. Connect your control signals to the _IN pads of this board, and connect the GND from your controller to the GND1 pad. This was designed to be controlled by +5V I/O, but it should work with +3.3V also for lighter loads.
