WS2818 Pixel LED Strip

What is WS2818?

WS2818 is a 3-channel LED driver control circuit, including a smart digital port data latch and a signal reshaping amplifier drive circuit. The reshaping of the amplified drive chain includes a precision internal oscillator and a programmable 12V voltage. Constant current control elements help to achieve highly consistent color effects. WS2818 has a good function in continuous transmission of signal breakpoints and adopts dual signal transmission. These signals can work together without interference. The user can choose the first DIN/BIN chip as the controller. The signal input pin and subsequent cascaded chips will automatically recognize the output signal generated by the first chip.

How does it work?

It uses an optimized signal shaping circuit to form the signal waveform, so there will be no message waveform distortion. It has a built-in reset and reset power-on circuit. There are 256-layer grayscale standards, and the refresh rate of each pixel is up to 2KHz/s. Both tasks are performed through a continuous signal line: serial cascade, data collection and decoding. The continuous propagation of the signal and the loss of any pixels will not affect the complete display effect. No other circuits are needed for any two transmission stations shorter than 5 meters. The ripple is no less than 1024 pixels, and the refresh rate is 30fps. It downloads data at a rate of 800Kbps. Quality is an excellent performance of strong cost-effectiveness. WS2818 is a 3-channel LED driver control circuit, involving automatic locking of smart port data and amplifying signal shaping circuit. It includes a precision internal oscillator and a programmable 12V voltage controlled by a constant current, which can produce very consistent color effects.

WS2818 Wiring Diagram

WS2818 is a 3-channel LED driver control circuit, including a smart digital port data latch and a signal reshaping amplifier drive circuit. It also includes a precision internal oscillator and a programmable 12V voltage constant current control component to achieve highly consistent color effects. WS2818 uses dual signal transmission, so these signals can work together without interference. However, if one signal is interrupted for some reason, the other signal still exists, and any single pixel failure will not affect other pixels, will not produce excessive display effects, and will not produce waveform distortion.

What are the advantages of WS2818?

1. Signal breakpoints are continuously transmitted. When one pixel is damaged, it will not affect the operation of the other LED.

2. Using the controller, any flash effect can be achieved.

3. The price is close to WS2811, but it has more resumable transmissions than WS2811.

4. Using a flexible PCB board, it can be folded into any shape.

5. It is 5 meters long and the LEDs are encapsulated in weatherproof silicone. Therefore, they can stay outside without being affected by rain and dust.

6. This is the coolest type of LED strip. You can individually control the color and brightness of each group of LEDs, which enables you to produce amazing and Complex effects in a simple way.

7. This strip is very flexible and can be cut into any length. You can adjust its size by cutting off the strip with scissors at the appropriate place. These strips have connectors at both ends.

8. The LED light bar should use 12V power supply.
