## Description

## Overview

The WS2812B RGB LED Ring is a circular PCB with 12 individually addressable WS2812B RGB LEDs arranged in a 50mm diameter ring. Each LED can display any color from a 24-bit palette (16.7 million colors), controlled via a single data wire. Multiple rings can be daisy-chained for larger configurations.

## Key Specifications

| Parameter | Value |
|-----------|-------|
| LED Type | WS2812B (addressable RGB) |
