The Blaster Bit reference design connects to the Neopixel Blaster. With ARC you can create colorful Blaster bit animations! A unique feature of the blaster bit is that it has a 5V regulator on-board so that it can be powered by, or protected from, higher voltages. We want to share these files with you so you can create your own!
