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.

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.

Every ring is equipped with a single data line with a very timing-specific protocol requiring a real-time microcontroller with an 8MHz or faster processor such as an AVR, Arduino, PIC, mbed, etc. There are solder pads on the back for connecting wires or breadboard pins and two mounting holes for securing this board to many different surfaces.


  • Working voltage: DC 4-7 V

Package List:

  • 1 x WS2812B RGB LED 24 bit Ring
