One of the goals this year was to really lower the barrier to entry for hacking on this badge! In addition to the NeoPixel Jewels on the outside, on the inside you’ll find a Trinket Mini 5V and some other goodies. The Trinket and Jewels are not soldered onto the board to make it easy to remove and use on your other projects! Or play around with the source and add your own features! (two extra pins on the board are just begging for some love.)
Here's some handy links if you want to explore the badge.
* triBB01 uses a modified version of the Neopixel library to save space. Not all functionality is present.
