The Neopixel Blaster reference design connects WS2812b addressable RGB LEDs to ARC. By utilizing ARC, the Neopixel Blaster can create animations and display all kinds of colors with WS2812b LEDs. A unique feature of this board is that it allows any ARC compatible board to use Neopixel LEDs, no libraries or precision timing required. We want to share these files with you so you can create your own!
