WS2812B RGB LED full color drive 4 foot lantern module development board

main feature

●      Intelligent reverse connection protection, reverse power connection will not damage the IC.

● The      IC control circuit shares a power supply with the LED point source.

● The      control circuit and RGB chip are integrated in a 5050 package component to form a complete external control pixel.

●      Built-in signal shaping circuit, after any pixel receives the signal, it is waveform-shaped and then output to ensure that the line waveform distortion will not be accumulated.

●      Built-in power-on reset and power-down reset circuit.

●      The three primary colors of each pixel can realize 256levels of brightness display, complete the true color display of 16777216 colors , and the scanning frequency is not less than 400Hz/s .

●      Serial cascade interface, which can receive and decode data through one signal line.

● There      is no need to add any circuit when the transmission distance of any two points is less than 5 meters.

●      When the refresh rate is 30 frames/second, the number of cascades is not less than 1024 points.

●       Data transmission speed can reach 8 00Kbps .

●       The color of light is highly consistent and cost-effective.

Main application areas

●      LED full color luminous word string, LED full color module, LED full color soft light strip hard light bar, LED guardrail tube.

●    LED point light source, LED pixel screen, LED shaped screen, various electronic products, electrical equipment marquee.

product description 

WS2813B is an intelligent external control LED light source integrating control circuit and light-emitting circuit. Its appearance is the same as a 5050 LED lamp bead, and each component is a pixel. The pixel includes an intelligent digital interface data latch signal shaping and amplifying driving circuit, and also includes a high-precision internal oscillator and a 12V high-voltage programmable constant current control part, which effectively ensures that the color of the pixel point light is highly uniform.

The data protocol adopts the single-line return-to-zero code communication mode. After the power-on reset, the DIN terminal accepts the data transmitted from the controller. The first 4bits of data sent by the first pixel are extracted and sent to the pixel. The internal data latch, the remaining data is shaped and amplified by the internal shaping processing circuit, and then forwarded to the next cascaded pixel through the DO port. The signal is reduced by 2 4 bits after each pixel transmission . The pixel adopts automatic shaping and forwarding technology, so that the number of cascaded pixels is not limited by signal transmission, and only the signal transmission speed is limited.

LED has low voltage drive, environmental protection and energy saving, high brightness, large scattering angle, good consistency, ultra low power, long life and so on. By integrating the control circuit on the LED, the circuit becomes simpler, smaller, and easier to install.
