What Are WS2812B LED Strip Lights?

WS2812B is a common RGB LED light strip. Each lamp bead has a chip control inside, which controls its on and off by sending specific timing data. When sending data, 24-bit RGB data needs to be sent in a certain timing, with the high bit in front and the low bit in the back, and the format is GRB. When sending data, you need to pay attention not only to send high level or low level, but to send PWM waves with different duty cycles, such as giving a certain high level and low level time. The reset code is to send a low level signal that lasts for 280us. You can send a set of 24-bit data first, and then receive a reset signal to indicate the end of the set. The data adopts a single bus and return-to-zero code communication method. Each pixel receives 24-bit data, and the overflow data is transmitted to the next pixel.

The WS2812B is a very popular programmable RGB LED (color light emitting diode) chip with integrated control circuitry and three LED (red, green, blue) elements. The WS2812B, also known as NeoPixel, is an LED component widely used by makers and electronics enthusiasts around the world.


Key features of the WS2812B include:

Integrated control: The WS2812B chip integrates the control circuitry of each LED, which means that each WS2812B LED can be independently programmed and controlled.

Can be cascaded: WS2812B LEDs can be connected in cascade, and the data output of one WS2812B LED can be connected to the data input of the next WS2812B, thereby realizing the series connection of multiple LEDs.

High Brightness and Colorful: The WS2812B LED has high brightness and can produce saturated red, green and blue light, allowing for a variety of color mixes.

Digital Control: Controlling the color and brightness of the WS2812B is via digital signals, meaning you can program them using a microcontroller or other digital electronics.

Wide range of uses: WS2812B LEDs are used in a variety of applications including lighting effects, decoration, artwork, indoor and outdoor decoration, electronic prototyping and more.

A common method of controlling WS2812B LEDs is to use a microcontroller or microcontroller to control the color and brightness of each LED by sending data in a specific format to the WS2812B. This data format is typically serial and requires ensuring correct timing and protocol to properly control each LED.

12. Dimmable

The WS2812B LED strip light can be easily dimmed to adjust the brightness level according to specific requirements. This allows for creating different atmospheres or moods by controlling the intensity of the light. Dimming also contributes to energy savings as it reduces power consumption when full brightness is not required.

13. Low Heat Emission

Compared to traditional lighting technologies, the WS2812B LED strip light emits very little heat. This is because LEDs convert most of the electrical energy into light rather than heat, resulting in reduced cooling requirements and minimized fire hazards

Disadvantages Of WS2812B LED Strip Lights


The WS2812B LED strip is more complex than a traditional LED strip and requires additional programming to control the color and brightness of each LED.


The WS2812B LED strip is more expensive than a traditional LED strip due to the added complexity of the WS2812B chip.

3.Data transfer rate

The WS2812B LED strip has a relatively low data transfer rate, which can limit the number of LEDs that can be controlled by a single microcontroller or other programmable device.

4.High power requirements

The WS2812B chip has high power requirements, and the power supply needs to be stable and powerful to ensure the normal operation of each chip.

5.Refresh frequency limitation

Due to the limitations of the communication protocol, the refresh frequency of WS2812B is relatively low, and refresh delays may occur when controlling a large number of LEDs.

6.A single point of failure has a large impact

Because the WS2812B chips are connected in series, when a certain chip fails, it may affect the normal operation of the entire series link.

It should be noted that the above is a discussion of the advantages and disadvantages of the WS2812B chip itself. In actual use, it needs to be comprehensively considered based on specific application scenarios and needs.

How to Choose the Right WS2812B LED Strip

1. LED Strip Type

WS2812B LED strips come in various types, such as flexible, rigid, and pixel tapes. Flexible strips are ideal for irregular surfaces, while rigid ones are more suitable for straight installations. Pixel tapes have LEDs spaced apart, offering greater flexibility in unique lighting designs.

2. LED Density

LED density refers to the number of LEDs per meter on the strip. Higher density translates to better color blending and smoother lighting effects. However, it also increases power consumption and cost. Choose the LED density based on your specific lighting requirements and budget.

3. Length

Consider the length of the LED strip you need for your project. Some strips come in predefined lengths, while others are customizable to fit your desired dimensions. Measure the area you wish to install the strip and ensure you purchase the appropriate length.

4. Power Requirements

WS2812B LED strips require sufficient power to operate correctly. Determine the power consumption per meter of the strip and ensure that your power supply can handle the load. It is advisable to provide some overhead power capacity to prevent voltage drop and maintain the brightness of the LEDs.

5. Voltage

Typically, WS2812B LED strips operate on a 5V DC voltage. However, some variations may use 12V or 24V. Ensure that your power supply matches the required voltage of the strip you choose to avoid damaging the LEDs or encountering flickering issues.

6. Waterproof Rating

Depending on your installation environment, you may need a waterproof WS2812B LED strip. Waterproof strips are suitable for outdoor or damp environments, while non-waterproof ones are more appropriate for indoor use. Ensure that the IP rating (Ingress Protection) meets your needs.

7. Control Interface

WS2812B LED strips require a microcontroller or special WS2812B controllers to control the individual LEDs. Consider the type of control interface you prefer, such as SPI, UART, or USB. Some strips are compatible with popular development boards like Arduino, making them easier to integrate into your project.

8. Compatibility

Ensure that the WS2812B LED strip you choose is compatible with the programming language and software you plan to use for controlling the LEDs. Most strips work well with common programming libraries and software development environments.
