Neopixel Round 7x WS2812 RGB LED

This round NeoPixel module carries 7 RGB LEDs (5 × 5 mm) with integrated WS2812 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
• Electrolytic capacitor 1000 µF 25 V

Features:

• 6 solder pads on the back, two each for VCC and GND
• 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:

• Small, bright light source in your own projects
• Lighting for model making
• Status and signal lights
