WS2812B-2020 datasheet & strip

Key Features of the WS2812B-2020 LED

The WS2812B-2020 is a compact, high-performance RGB LED that’s perfect for creating vibrant lighting effects. With an integrated driver, each LED can be individually controlled, allowing for dynamic color-changing displays. Its small 2020 package size (2.0mm x 2.0mm) makes it ideal for space-constrained projects. The WS2812B-2020 operates on a 5V power supply and uses a single-wire communication protocol, simplifying connections. Whether you’re building a lighting display, custom signage, or interactive projects, this LED is a great choice for low-power, high-impact designs.

WS2812B-2020 Pinout

Using the WS2812B-2020 Pinout

The WS2812B-2020 is a simple-to-use, individually addressable RGB LED. 電源電壓 (Pin 1) provides the 5V power supply to the LED, while 接地 (Pin 2) connects to the common ground. The Data In (Pin 3) pin receives the control signal, which tells the LED what color and brightness to display. If you’re chaining multiple LEDs together, Data Out (Pin 4) sends the signal to the next LED in the sequence. Make sure to use proper voltage levels and always connect the ground pin to avoid communication issues.

Substitution Tips

When replacing the WS2812B-2020, look for models with similar voltage rating, color depth， 和 communication protocol to ensure compatibility. Models like the SK6812-2020 offer the additional benefit of white color (RGBW), which can be useful for pure white lighting. The WS2813-2020 offers a similar performance but features an upgraded backup data line for better signal reliability. If you prefer a two-wire setup, the APA102-2020 is a solid alternative with a separate clock line for smoother data transmission. Always verify the power consumption 和 package size to ensure the replacement fits your design needs.

How It Works

The WS2812B-2020 operates using a single-wire communication protocol. Data is input through the DIN pin, which is connected to the data output of the previous LED or controller. The data is then processed by the internal control circuit, which adjusts the RGB values of the LED. 這 DOUT pin outputs the processed data to the next LED in the chain.

Each LED requires a 5V power supply, connected to the 電源電壓 pin, and ground, connected to the 接地 pin. A small capacitor (typically 100nF) is recommended between the 電源電壓 和 接地 pins to stabilize the power supply and reduce noise.

For optimal performance, ensure that the data signal is clean and within the specified voltage levels. Using a level shifter may be necessary if the controller operates at a lower voltage than the WS2812B-2020.

This configuration allows for easy cascading of multiple WS2812B-2020 LEDs, enabling the creation of large, vibrant displays with minimal wiring.
