This ring has 12 WS2812 RGB LEDs evenly spaced around the white PCB. We've worked with leading LED manufacturers to ensure these are of the highest quality and that they are fully compatible with the Adafuit NeoPixel library you know and love using! This ring has 4 pre-soldered connections so it's easy to get the ring lit up in no time. With a V+, GND and DATA IN & OUT connection they're driven from a single line making them perfect for use with controllers with limited output pins and daisy chaining together.
