4-Pin WS2812B sk6812 LED Chip Heatsink Board 5V 5050 RGB WS2811 IC Built-in RGBW

  
Note: There is no welding between each pixel lamp beads, if you want them work togehter, you need welding by yourself. L Intelligent reverse connect protection, the power supply reverse connection does not damage the IC. L The control circuit and the LED share the only power source. L Control circuit and RGB chip are integrated in a package of 5050 components, form a complete control of pixel point. L Built-in signal reshaping circuit, after wave reshaping to the next driver, ensure wave-form distortion not accumulate. L Built-in electric reset circuit and power lost reset circuit. L Each pixel of the three primary color can achieve 256 brightness display, completed 16777216 color full color display, and scan frequency not less than 400Hz/s. L Cascading port transmission signal by single line. L Any two point the distance more than 5m transmission signal without any increase circuit.

L When the refresh rate is 30fps, cascade number are not less than1024 points. L Send data at speeds of 800Kbps. L The color of the light were highly consistent, cost-effective. Led CHIP Built-in Heatsink Board.
