Overview

The NeoPixel Ring 2855 is a circular array of 16 individually addressable 5050-sized LEDs with integrated drivers. This variant features RGBW pixels, combining standard Red, Green, and Blue with a dedicated Natural White (4500K) element for superior color mixing and pure white illumination.

Why Choose This Part

The integrated constant current drivers ensure consistent brightness even if battery voltage fluctuates, and the single-wire control protocol minimizes GPIO usage. Adding a fourth white channel provides a broader color gamut and higher quality white light than traditional RGB mixing.

Applications

Status Indicators
Circular light patterns to indicate progress, levels, or system states in user interfaces.
Decorative Lighting
High-density color and white lighting for cosplay, wearable electronics, or architectural accents.
Light Painting
Long-exposure photography tools utilizing programmable color sequences and circular geometries.

Getting Started

Power the ring with 5V DC and connect the data input to a 5V logic microcontroller pin. Use the Adafruit_NeoPixel library in the Arduino IDE to address individual pixels, ensuring you select the 'NEO_RGBW' pixel type in your software initialization.
