Product Description The 16-Bit WS2812B RGB LED Ring is a powerful and visually stunning circular development board designed for advanced lighting effects. Each of the 16 LEDs on this ring features a built-in WS2812B driver IC, allowing every single pixel to be controlled independently for color and brightness through just one digital pin on your microcontroller. This "daisy-chainable" design means multiple rings can be connected together while still using only one data line. Whether you are building a futuristic steampunk prop, a smart clock, or a robotic "eye" effect, this ring provides high-intensity, uniform light in a compact and easy-to-mount circular format.
Key Highlights
Individually Addressable: Control the color and brightness of each of the 16 LEDs separately to create complex animations and patterns.
Single-Wire Control: Uses a high-speed serial protocol that requires only one data pin (DI), significantly saving I/O pins on your Arduino or ESP32.
Vibrant Full-Color Output: Integrated 5050 RGB chips offer a wide color gamut with 256 levels of brightness for each color channel.
Intelligent Driver Timing: The built-in WS2812B IC handles all the PWM timing internally, ensuring flicker-free lighting without taxing your CPU.
Expandable Design: Features both Data Input (DI) and Data Output (DO) pads, allowing you to chain multiple rings together for larger displays.

Installation Tip from Robogears While these LEDs are incredibly bright, running all 16 at full white brightness simultaneously can draw nearly 1 Amp of current. We recommend powering the ring directly from a high-quality 5V power supply rather than through the Arduino's 5V pin to prevent voltage drops or overheating. Additionally, place a 470$\Omega$ resistor between your microcontroller’s data pin and the ring's DI pin, and a 1000$\mu$F capacitor across the power lines to protect the LEDs from voltage spikes.
