WS2812B may be a intelligent control Mini LED light that the negative feedback circuit and RGB chip are integrated during a package of 5050 components. It internal include intelligent digital port data latch and signal reshaping amplification drive circuit. Also include a precision internal oscillator and a 12V voltage programmable constant curre-nt control part, effectively ensuring the pixel point light color height consistent.
The data transfer protocol use single NZR communication mode. After the pixel power-on reset, the DIN port receive data from controller, the primary pixel collect initial 24bit data then sent to the interior data latch, the opposite data which reshaping by the interior signal reshaping amplification circuit sent to subsequent cascade pixel through the DO port. After transmission for every pixel,the signal to scale back 24bit. pixel adopt auto resha-ping transmit technology, making the pixel cascade number isn’t limited the signal transmission, only depend upon the speed of signal transmission.
LED with low driving voltage, environmental protection and energy saving, high brightness, scattering angle is large, good consistency, low power, long life and other advantages. The control chip integrated in LED above becoming more simple circuit, small volume, convenient installation.
5050 RGB LED Mini PCB Features and Benefits：
- Intelligent reverse connect protection, the facility supply reverse connection doesn’t damage the IC.
- The negative feedback circuit and therefore the LED share the sole power source.
- Control circuit and RGB chip are integrated during a package of 5050 components, form an entire control of pixel point.
- Built-in signal reshaping circuit, after wave reshaping to subsequent driver, ensure wave-form distortion not accumulate.
- Built-in electric reset circuit and power lost reset circuit.
- Each pixel of the three primary color are able to do 256 brightness display, completed 16777216 color full color display, and scan frequency not but 400Hz/s.
- Cascading port transmission signal by single line.
- Any two point the space quite 5m transmission signal with none increase circuit.
- When the refresh rate is 30fps, cascade number aren’t less than1024 points.
- Send data at speeds of 800Kbps.
- The color of the sunshine were highly consistent, cost-effective..
