Kitronik WS2812B

[WORLDSEMI CO., LIMITED]

General description

WS2812B is a intelligent control LED light source that the control circuit and RGB chip are integrated in a package of 5050 components. It internal include intelligent digital port data latch and signal reshaping ampli fication drive circuit. Also include a precision internal oscillator and a 12V voltage programmable constant curr e-nt control part, effectively ensuring the pixel point light color height consistent.

Features and Benefits

● Intelligent reverse connect protection, the power supply reverse connection does not damage the IC.
● The control circuit and the LED share the only power source.
● Control circuit and RGB chip are integrated in a package of 5050 components, form a complete control of pixel point.
● Built-in signal reshaping circuit, after wave reshaping to the next driver, ensure wave-form distortion not accumulate.
● Built-in electric reset circuit and power lost reset circuit.
● 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.
● Cascading port transmission signal by single line.
● Any two point the distance more than 5m transmission signal without any increase circuit.
● When the refresh rate is 30fps, cascade number are not less than1024 points.
● Send data at speeds of 800Kbps.
● The color of the light were highly consistent, cost-effective..

Applications

● Full-color module, Full color soft lights a lamp strip.
● LED decorative lighting, Indoor/outdoor LED video irregular screen.
