Neopixel Ring 8x WS2812B RGB LED

This 8 Bit NeoPixel Ring is equipped with small RGB LEDs (5x5mm). On the back side there are solder pads which can be easily soldered with the control wires. Multiple NeoPixels can be connected in a row and each LED can be easily controlled via an output by a microcontroller, e.g. Arduino UNO, Mega, Nano etc. There are also many programming examples, just search for NeoPixel or Fastled. We recommend to connect a 3300 µF capacitor between GND and 5V to ensure a stable voltage supply and thus also the lifespan of the LED.
