From the project

DMX Demonstrator

The Constant Current LED Driver is stand-along module which takes 2 logic signals and amplifies the output for a larger current load such as an led chip. Most led chips require a constant current as opposed to a constant voltage, this board implements a constant-current driver using the AL8660/AL8661 led driver module. It can be modified to provide 350ma, 700ma, or 900ma depending on the needs of your led.
