50-Pack Programmable RGB SMD LED Pixel Chip Beads (WS2812B Compatible)

Take your LED lighting projects to the next level with this 50-piece set of built-in IC programmable RGB LED pixel chip beads. Compatible with WS2812B protocols, these compact SMD 6028/3528 components integrate the control circuit and LED chip into a single unit — giving you precise, uniform color output with minimal wiring complexity. Perfect for DIY electronics, custom keyboard builds, LED strips, decorative lighting arrays, and maker projects.

Made in Mainland China.

Key Features

• Built-in IC Control: Single-line serial cascade constant current IC integrated directly into each SMD chip — no external controller IC needed per pixel.
• Unlimited Cascading: Chain as many pixels as your project requires; at 30 frames/second refresh rate, supports cascades of 1,024+ points.
• Data Shaping Circuit: Every pixel reshapes the signal before forwarding it, preventing waveform distortion from accumulating along the chain.
• Power-On/Off Reset: Built-in reset circuits ensure LEDs remain off at startup until a valid data signal is received.
• 256-Level Grayscale: Full 256-step grayscale adjustment per color channel delivers smooth, precise color rendering and balanced color mixing.
• High-Speed Data Transmission: Supports data rates up to 800 Kbps for fast, flicker-free updates.
• Long-Range Signal Forwarding: Shaping forwarding enhancement technology allows point-to-point transmission distances exceeding 10 meters.
• Balanced Red Drive: Special red-channel treatment ensures more accurate, balanced color matching across all hues.
• Compact Form Factor: Ultra-small 0.6 × 0.2 cm (approx. 0.24 × 0.08 in) SMD package fits tight PCB layouts and high-density installations.

Frequently Asked Questions

Q: Are these LED chip beads fully compatible with WS2812B controllers and libraries?

A: Yes — these SMD pixel LED chips are designed to be fully compatible with WS2812B protocols. They work with popular microcontrollers and libraries such as FastLED and Adafruit NeoPixel that support WS2812B single-wire data transmission.

Q: How many LED pixel chips can I chain together?

A: These chips support unlimited cascading in theory. At a 30 frames-per-second refresh rate, the cascade count is rated at 1,024 points or more, making them suitable for large LED matrix and strip projects.

Q: What is the maximum signal transmission distance between two chips?

A: Thanks to built-in shaping forwarding enhancement technology, the signal can reliably travel more than 10 meters between two pixel points — ideal for longer LED installations without signal boosters.

Q: Do these LEDs turn on automatically when power is applied?

A: No. Each chip features built-in power-on and power-off reset circuits that keep the LED off until a valid data signal is received, preventing unwanted flashes or startup glitches.
