WS2812B Neopixel Addressable RGB LED – 5050

WS2812B Neopixel Addressable RGB LED – 5050 is a popular and powerful lighting component that gives you total control over color and brightness. Each LED contains a smart control IC right inside the 5050 package, allowing you to individually address and program every single one on a strip or matrix. This digital LED chip simplifies complex lighting projects, as a single microcontroller data pin can drive hundreds of LEDs, making it a favorite for hobbyists and professionals who want to create dynamic and vibrant displays.

Key Features:

• Individual Addressability: You can control the color and brightness of each LED independently using a single data wire.
• Full RGB Color Spectrum: Delivers 24-bit color depth (8 bits per R, G, and B channel) for over 16 million colors.
• High Brightness: Emits brilliant and vibrant light, making it suitable for both ambient and display applications.
• Cascading Design: Easily daisy-chain multiple LEDs together by connecting the DOUT pin of one to the DIN pin of the next.
• Built-in Driver IC: Integrates the driver chip directly into the LED package, simplifying wiring and reducing the component count.
• High Refresh Rate: Achieve smooth animations and quick color changes with a data transfer speed of up to 800Kbps.

Technical Specifications:

• Operating Voltage: 4 V to 7 V (typical 5 V)
• LED Current: ~18.5 mA per color (R/G/B) at full brightness
• Color Depth: 24 bits (8-bit per channel)
• Data Protocol: One-wire protocol
• Data Transfer Speed: 800 Kbps
• Operating Temperature: -25 °C to +80 °C

Mechanical Specifications:

• Package Type: 5050 Surface-Mount Device (SMD)
• Pin Count: 4 pins
• Assembly: Designed for surface soldering to PCBs or pre-assembled on flexible strips.
• Material: Plastic LED casing with integrated IC.

Dimensions:

• Length: 5.0 mm
• Width: 5.0 mm
• Height: ~1.6 mm

Pinout and Wiring:

• VDD: Power supply (5 V typical)
• VSS: Ground
• DIN: Data input line
• DOUT: Data output line for cascading to the next LED’s DIN pin
• Wiring Note: Connect VDD and VSS to a stable 5V power source. Wire a single microcontroller pin to the DIN of the first LED. Daisy-chain subsequent LEDs from the DOUT pin of the previous LED.
