WS2812B RGB LED 24 Bit Ring

This is the 24 LED NeoPixel Ring, a small chainable 86mm outer diameter board equipped with 5050 WS2812 RGB LEDs. The WS2812s are each addressable as the driver chip is located inside the LED. Each NeoPixel Stick has ~18mA constant current drive so the color will be very consistent even if the voltage varies, and requires 5 V.
