WS2812B RGB 4020SMD Side Lighting Individually Digital Addressable LED Chip, DIY LED Chip, 500PCS By Sale

How does WS2812B LED works?

WS2812 is a collection of control and luminous LED light source, the appearance of the LED chip is SMD4020, and each element is a pixel. Serial single-wire cascade interface, data protocol using single-wire zero code communication mode, after the pixel is reset at power on, the DIN side accepts the data transmitted from the SPI controller, and the bit in the transmission is the same as that of the LED after the pixel is reset at power-on, the DIN terminal accepts the data transmitted from the controller, the bit data is extracted from the first pixel and stored in the data latch, the remaining data is shaped and amplified by the internal shaping processing circuit and then forwarded to the next cascade pixel through the DO port, every time a pixel is transmitted, the bit signal is weakened, and the number of cascaded pixels is only limited by the signal transmission speed.

Product Feature

Top SMD integrates high-quality externally controlled single-wire serial cascaded constant current IC;

The control circuit and chip are integrated into the SMD4020 components to form a complete external control pixel, with uniform color temperature effect and high consistency.

Built-in data shaping circuit, any pixel point receives the signal after waveform shaping and then output, to ensure that the road waveform distortion will not accumulate.

Built-in power-on reset and power-down reset, the light does not light up after power-on;

Grayscale adjustment circuit (256 levels of grayscale can be adjusted),

Red light drive special processing, the color matching is more balanced,

Single wire data transmission, unlimited cascading.

Reshaping and forwarding enhancement technology, the transmission distance between two points exceeds 10M.

The data transmission frequency can reach 800Kbps. When the refresh rate is 30 frames per second, the cascade number is 1024 points.
