Neopixel Ring 8x WS2812B RGB LED

This NeoPixel ring carries 8 RGB LEDs (5 × 5 mm) with integrated WS2812B driver. Solder pads for the connection wires are on the back. Several NeoPixels can be chained. Each LED is controlled individually via a single output of a microcontroller such as Arduino UNO, Mega or Nano.

Recommended Accessories:

• Stranded Wire Assortment 22AWG SparkFun
• Resistance Set 600 pcs. Assorted 1/4W 1% Accuracy
• Electrolytic capacitor 1000 µF 25 V

Features:

• 4 solder pads on the back: DI, 5V, GND, DO
• Each LED individually controllable via one data line
• Several modules can be chained (data output to data input)
• Library: FastLED or Adafruit NeoPixel
• 300 to 500 Ω resistor in the data line recommended
• With 3.3 V boards, a level shifter on the data line is recommended
• 500 to 1000 µF capacitor on the power supply recommended

Application Examples:

• Circular displays, for example clocks or progress indicators
• Lighting for model making
• Light effects in your own projects
