It's a microcontroller kit. It's a 3 watt RGB LED kit. Put into a blender with an appropriate amount of solder and love, it turns into a microcontrolled Northern Lights RGB Bundle! This little guy can produce greens, violets, and teals that make you feel like you're north of the 49th parallel.
We've had some requests for a common Anode RGB LED, you asked, we delivered! So instead of the common pin going to ground it will go to Vcc and the signal wires go low (to ground). It seems backward to normal convention but some people like to roll that way!
