LilyPad is a wearable technology developed by Leah Buechley and cooperatively designed by Leah and SparkFun.
Each LilyPad was creatively designed to have large connecting pads to allow them to be sewn into clothing.
Various input, output, power, and sensor boards are available.
Very bright output. This is a common anode design - to turn on a channel you simply need to ground one of the R/G/B pins to illuminate that channel.
