Quick Answer

The WS2812B-2020-V6 is a 2.0×2.0mm addressable RGB LED that integrates the control IC and light-emitting chip in a single package. It features 256-level brightness per channel, 16.7 million colors, 2KHz port scanning frequency, and a data transfer rate of 800Kbps. With a built-in signal reshaping circuit, reverse polarity protection, and static power consumption below 1μA, it is designed for dense pixel applications where space is limited.


Introduction: A Smaller Package for Denser Pixels

As pixel lighting applications become more demanding — higher resolution, tighter spacing, smaller form factors — the LED package itself must evolve.

The WS2812B-2020-V6 answers that need. It puts a complete addressable RGB pixel into a 2.0 × 2.0mm package, making it suitable for applications where traditional 5050 or 3535 LEDs are too large.

This article covers its key features, specifications, and applications.


What Is the WS2812B-2020-V6?

The WS2812B-2020-V6 is an intelligent external-control integrated LED light source. It combines:

  • A control IC

  • RGB LED chips

  • Signal shaping and forwarding circuitry

All in a single 2020 (2.0 × 2.0mm) package. Each unit functions as one addressable pixel.

The package uses a molding process to integrate the IC and light-emitting chip, delivering high color consistency and reliable performance.


Key Features

1. Integrated Control IC and LED – One Complete Pixel

Each WS2812B-2020-V6 is a complete pixel point. The control circuit and RGB chip are integrated in a single package, simplifying circuit design and reducing component count.

2. 256-Level Brightness per Channel – 16.7 Million Colors

Each of the three color channels (Red, Green, Blue) supports 256 levels of brightness, producing 16,777,216 possible colors for full-color display.

3. Built-In Signal Reshaping – No Waveform Distortion Accumulation

The IC includes a signal reshaping circuit. When a pixel receives data, it reshapes the waveform before forwarding it to the next pixel — ensuring that signal distortion does not accumulate across long chains.

4. 2KHz Port Scanning Frequency – Flicker-Free

With a 2KHz port scanning frequency, the WS2812B-2020-V6 produces no visible flicker — even under high-speed camera capture. This makes it suitable for applications involving video recording or fast-moving displays.

5. 800Kbps Data Transfer Rate – Fast and Reliable

The data transmission rate reaches 800Kbps. At a refresh rate of 30 frames per second, the cascade count is no less than 1024 pixels.

6. Built-In Power-On and Power-Off Reset Circuits

The IC includes automatic power-on reset and power-off reset circuits, ensuring reliable startup and shutdown behavior.

7. Reverse Polarity Protection – No Damage from Reversed Power

The WS2812B-2020-V6 is designed to withstand reverse power connection without damage — a practical advantage during installation and troubleshooting.

8. Dual-Direction Signal Input – DI and DO Can Be Switched

The data input (DI) and data output (DO) can be switched in either direction, providing flexibility in wiring and layout.

9. Ultra-Low Static Power Consumption – Below 1μA

Static power consumption is less than 1μA, making the LED suitable for low-power and battery-sensitive applications. It also supports 3.3V supply voltage.

10. 280μs Reset Time – Reliable Data Transmission

The reset time is 280μs or longer, which prevents false resets during interruptions and allows compatibility with lower-cost, lower-frequency MCUs.
