Description
These WS2812B RGB LED chips are 4 pin 5050 SMD intelligent addressable LEDs with an integrated control circuit inside each LED.
Each chip can be individually controlled to produce over 16 million colours, making them ideal for custom lighting, display projects, wearables, or decorative effects.
The WS2812B combines an RGB LED and a control IC in a single package, simplifying wiring and control.
It communicates over a single data line, making it perfect for cascading multiple LEDs together with minimal I/O usage.

What’s Included:
- 10 x WS2812B 4-Pin 5050 SMD Addressable RGB LED Chips (White PCB)
Great For:
- Custom LED light strips and matrices
- Wearable and decorative tech
- Interactive displays and mood lighting
- DIY electronics and microcontroller projects (Arduino, ESP32, Raspberry Pi)
Usage Tips:
- Use a level shifter if your microcontroller operates at 3.3V (WS2812B is 5V logic level)
- Add a 1000µF capacitor across VCC and GND and a 330Ω resistor on the data line for stable operation
- Use appropriate libraries like FastLED or Adafruit NeoPixel for easy coding
