50Pcs WS2812B RGB SMD Pixel LED Chips Built-In IC Programmable
50Pcs Programmable RGB SMD Pixel LED Chips (6028/3528, WS2812B Compatible)
Take your lighting projects to the next level with these high-performance programmable RGB SMD pixel LED chips. Compatible with the WS2812B protocol, each chip integrates the control circuit and IC directly into the compact SMD 3528 package — giving you vibrant, consistent, full-color illumination with minimal wiring complexity. Perfect for keyboards, LED strips, DIY electronics, custom lighting installations, and maker projects. Made in Mainland China.
Key Features
- Built-In Control IC: Single-line serial cascade design integrates the control circuit and chip directly into each SMD component, making wiring clean and simple.
- Consistent Color Output: Uniform color temperature effect with high consistency across all pixels — ideal for large arrays and cascaded setups.
- Built-In Data Shaping Circuit: Waveform shaping at every pixel point prevents signal degradation and waveform distortion from accumulating across the chain.
- Power-On / Power-Off Reset: Integrated reset circuits ensure LEDs do not illuminate unexpectedly during power cycling.
- 256-Level Grayscale Adjustment: Fine-tune each color channel with 256 steps of grayscale control for precise, accurate color matching.
- Balanced Red Drive: Special red-light drive treatment ensures more balanced and true-to-life color rendering.
- Unlimited Cascading: Single-line data transmission supports unlimited cascade connections — at 30 fps refresh rate, supports 1,024+ cascade points.
- Long Transmission Distance: Shaping forwarding enhancement technology supports point-to-point transmission distances exceeding 10 meters.
- High Data Rate: Data transmission frequency up to 800 Kbps for smooth, responsive color changes.

Frequently Asked Questions
Q: Are these WS2812B RGB LED chips fully compatible with standard WS2812B controllers and libraries?
A: Yes. These SMD pixel LED chips are designed to be WS2812B-compatible, using the same single-line serial cascade protocol. They work with popular microcontroller platforms (such as Arduino) and widely used LED libraries that support the WS2812B standard.
Q: How many of these RGB LED chips can I chain together?
A: These chips support unlimited cascading via single-line data transmission. At a 30 frames-per-second refresh rate, the cascade chain supports a minimum of 1,024 pixel points, making them suitable for large LED arrays and complex lighting installations.
Q: What is the maximum signal transmission distance between two pixels?
A: Thanks to the built-in shaping forwarding enhancement technology, the signal transmission distance between two points can exceed 10 meters (approximately 33 feet), reducing the need for signal repeaters in longer runs.
Q: What size are these SMD LED chips?
A: Each chip measures approximately 0.24 × 0.08 inches (about 6 × 2 mm), making them compact and suitable for use in tight spaces such as keyboard PCBs, wearables, and miniature LED displays.
