III description WS2812B is a intelligent management LED mild source that the management circuit and RGB chip are integrated in a package of 5050 components. It inner include clever digital port information latch and sign reshaping amplification drive circuit. Also consist of a precision inside oscillator and a 12V voltage programmable fixed curre-nt control part, effectively making certain the pixel point light color top consistent. The information move protocol use single NZR conversation mode. After the pixel power-on reset, the DIN port receive information from controller, the first pixel bring together preliminary 24bit data then despatched to the inner information latch, the other information which reshaping by way of the internal signal reshaping amplification circuit sent to the next cascade pixel in the process the DO port. After transmission for every pixel,the signal to play down 24bit. pixel adopt auto resha-ping transmit technology, making the pixel cascade number isn't always limited the signal transmission, only depend on the speed of signal transmission. LED with low using voltage, environmental protection and effort saving, excessive brightness, scattering perspective is large, good consistency, low power, lengthy existence and different advantages. The management chip included in LED above fitting easier circuit, small volume, useful installation. I and Benefits l Intelligent opposite connect protection, the flexibility supply contrary connection doesn't damage the IC. l The management circuit and the LED share the simplest power source. l Control circuit and RGB chip are incorporated in a equipment of 5050 components, variety a whole leadership of pixel point. l Built-in signal reshaping circuit, after wave reshaping to a higher driver, make certain wave-form distortion no longer accumulate. l Built-in electric reset circuit and gear lost reset circuit. l Each pixel of the three main coloration can obtain 256 brightness display, completed 16777216 color complete color display, and scan frequency not lower than 400Hz/s. l Cascading port transmission signal by means of single line. l Any two point the distance more than 5m transmission signal without any grow circuit. l When the refresh commission is 30fps, cascade number are not less than1024 points. l Send data at speeds of 800Kbps. l The coloration of the light were extremely consistent, cost-effective.. II l Full-color module, Full coloration smooth lighting fixtures a lamp strip. l LED decorative lighting, Indoor/outdoor LED video irregular screen. III description WS2812B is a clever control LED light source that the management circuit and RGB chip are incorporated in a kit of 5050 components. It internal consist of intelligent electronic port information latch and signal reshaping amplification power circuit. Also consist of a precision inside oscillator and a 5V voltage programmable fixed curre-nt control part, effectively making certain the pixel level mild shade top consistent. The information move protocol use unmarried NZR verbal exchange mode. After the pixel power-on reset, the DIN port acquire news from controller, the first pixel compile preliminary 24bit information then despatched to the inside information latch, the different data which reshaping through way of the inner signal reshaping amplification circuit sent to a better cascade pixel in the course of the DO port. After transmission for every pixel,the sign to reduce 24bit. pixel adopt auto resha-ping transmit technology, making the pixel cascade quantity isn't always restricted the sign transmission, entirely depend on the rate of sign transmission. LED with low riding voltage, environmental defense and effort saving, immoderate brightness, scattering perspective is large, nice consistency, low power, lengthy lifestyles and other advantages. The management chip incorporated in LED above becoming more uncomplicated circuit, small volume, handy installation. Package Included: 100/500/1000 Pieces WS2812B Chip(AS your choose)
