WS2812B 5V Addressable RGB LED SMD Chips – Full Color Pixel
WS2812B 5V Addressable RGB Full-Color LED Chips
Take your LED lighting projects to the next level with these high-performance WS2812B 5V addressable RGB LED chips. Available in a wide range of SMD package sizes — including 5050, 3528, 4020, 1204, 1209, 0807, and 2020 — these individually addressable digital pixel diodes give you full, precise control over every single LED in your design. Each chip integrates the control circuit and RGB LED into a single compact package, making them ideal for hobbyists, engineers, and professional makers alike.
Whether you're building custom LED strips, wearable electronics, display matrices, or decorative lighting installations, these chips deliver vibrant, true full-color output at a low 5V operating voltage with just 5mA current per channel. The built-in WS2812 controller supports cascading, so you can chain hundreds of pixels and control them all from a single data line.

Frequently Asked Questions
Q: What microcontrollers are compatible with WS2812B addressable LED chips?
A: WS2812B addressable LED chips are compatible with virtually any microcontroller that can output a 5V or 3.3V digital signal, including Arduino (Uno, Nano, Mega), ESP8266, ESP32, Raspberry Pi, and STM32. Popular libraries such as FastLED and Adafruit NeoPixel make programming these chips straightforward for beginners and professionals alike.
Q: Which SMD package size should I choose for my project?
A: The right package size depends on your PCB design and pixel density requirements. The 5050 package is the most common and easiest to hand-solder, making it great for general use. Smaller sizes like 2020, 1209, or 0807 are suited for high-density arrays or compact wearable electronics where space is at a premium. If you're unsure, contact our customer service for a full parameter table to compare the options.
Q: Can WS2812B LED chips be chained together?
A: Yes! One of the biggest advantages of the WS2812B is its single-wire cascade data protocol. You can chain hundreds — even thousands — of pixels together, controlling each one individually from a single data output pin on your microcontroller. This makes them extremely efficient for large lighting installations and display projects.
Q: What voltage do these LED chips require?
A: These WS2812B LED chips operate at 5V DC. This makes them ideal for USB-powered projects and easy integration with standard 5V microcontroller power supplies. Ensure your power supply can handle the total current demand when chaining multiple LEDs together in a large array.
