WS2812B-4 RGB LED module

Size: 15 mm * 15 mm

 

The main features

- Intelligent reverse connect protection, the power supply reverse will not damage the IC.

- IC Control circuit and LED point light utility a power supply.

- Control circuit and the RGB chip integration in a 5050 size components, constitute a complete external control pixels.

- Built-in signal shaping circuit, any pixels after received signal waveform shaping output again, ensure the line waveform distortion does not accumulate.

- Built-in electric reset and reset circuit when power supply drop.

- Each pixel of the three primary colors can be realized256, according to the level of brightness 16777216 The true colors of color displayNot less than 400 hz/s, the scanning frequency.

- Serial connection mouth, can complete data through a signal receiving and decoding.

- Any transmission distance in no more than two points5M without increasing any circuit.

- When the refresh rate of 30 frames per second, cascade number not less than 1024 points.

- Data speed can reach 800 KBPS.

- The color of light highly consistent, high performance-price ratio.

 

Main application fields

- The LED Full-color emitting light string, full-color LED modules, LED full-color soft article lamp hard light bar, LED guardrail tube.

- The LED Point light source, LED pixel screen, LED abnormity screen, all kinds of electronic products, electrical equipment entertaining diversions.

 

Product overview

 

- WS2812B is a collection of control circuit and light-emitting circuit in the integration of intelligent controlThe LED The light source.Its appearance and a5050 ledLights are the same, each element is a pixel.Pixel contains internal intelligent digital interface data latch signal shaping amplifier drive circuit, also contains a high precision internal oscillator and 12 v high pressure programmable constant current control part

- Data protocol adopts single size zero communication, pixels in electricity after reset,DIN Receive the data from the controller transfer to come over, send over the first two 4 -data After being extracted first pixel to pixel within the data latch, the remaining data through internal plastic processing circuit through after plastic amplificationThe DO Output port to forward to the next cascaded pixel, every pixel of transmission, signal by 24 -.Forward pixels using automatic plastic technology, makes the number of cascaded pixel is not restricted by the signal, only limited signal transmission speed requirements.

-The LED Low voltage driver, environmental protection and energy saving, high brightness, scattering Angle is big, good consistency and low power, long life, etc.To integrate the control circuit for leds, circuit become more simple, small size, installation easier.
