This small driver board allows you to control twelve 1W high power LED's or four 3W RGB LED's, like Luxeon or Rebel LED's.

The outputs of these drivers are constant current sinks that can be pulse widh modulated with ShiftPWM. You don't need resistors with these boards.

The boards can be chained to create more outputs. The outputs can also be grouped to drive 700 mA LED's.

On board are 3 STP04CM05XTTR LED drivers. Each driver has its own potentiometer to adjust the maximum current from 70 to 350 mA. You can use this to adjust the color balance for RGB LED's.
