GitHub - NLED/ws2801fet: Based on the WS2801 chipset this 3 channel MOSFET driver allows high current and/or high voltages(5v to 60v) to be controlled just like a standard WS2801 pixel. Great for controlling 12 volt RGB LED strips or other types of high wattage LEDs in various configurations. Operates just like any other pixel, so they can be chained together or controlled by themselves. Easy to interface to from an Arduino, PIC or other logic devices with a SPI port. The control scheme is simple, send 3 bytes of data for every module in the chain using a standard SPI port, waiting at least 500uS between updates. Or they can be controlled with one of the many NLED Pixel Controllers.
