Rainbowduino is a powerful and easy to use LED driver platform, you can easily light up a 8X8 RGB matrix with few steps, or control up to 192 LEDs by breaking out all pins on rainbowduino. But there’s still difficulties for a amateur to finish these in short time, and we want to make things easier, that’s why we built this Rainbowduino Extension Board.

The extension board can be easily stack on a rainbowduino, and we break out all pins to 3X8x8 area. We also added  eye catching silk screen on PCB so you can easily find out where you should get started.

Below is a demo video of Rainbowduino extension board with red, green and blue leds soldered.

This extension board will come out in kits, including the PCB and necessary pin headers. Those LEDs shows in picture will not be included.

Please let us know if you have any suggestions.
