Neopixel Ring Set with 1/8/12/16/24 WS2812B RGB LED

This set consists of 4 NeoPixel rings with 8, 12, 16 and 24 LEDs and a centre piece with 1 LED, a total of 61 RGB LEDs with integrated WS2812B driver. The parts can easily be broken out and fixed via mounting holes. Several NeoPixels can be connected in series. Each LED is controlled individually via a single output of a microcontroller such as Arduino UNO, Mega or Nano.

Recommended Accessories:

• 5V DC 4000mA plug-in power supply 5.5mm/2.1mm connector
• Electrolytic capacitor 1000 µF 25 V
• Resistance Set 600 pcs. Assorted 1/4W 1% Accuracy
• Stranded Wire Assortment 22AWG SparkFun

Features:

• Solder pads on the back of each part: DI, 5V, GND, DO, centre IN, VCC, GND, OUT
• Each LED individually controllable via one data line
• Several parts can be connected in series (data output to data input)
• Library: FastLED or Adafruit NeoPixel
• 300 to 500 Ω resistor in the data line recommended
• A level shifter for the data line is recommended on 3.3 V boards
• 500 to 1000 µF capacitor on the power supply recommended

Application Examples:

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