Worldsemi WS2812B-Mini RGB SMD LED - WS2812B-3535

Technical datasheet

WS2812B-Mini is an intelligent control LED light source that the control circuit and RGB chip are integratedinapackage of 3535 component. It internal include intelligent digital port data latch and signal reshaping amplificationdrivecircuit. It also includes a high-precision internal oscillator and a programmable constant current control part toensurehigh color consistency.

The data transfer protocol use single NZR communication mode. After the pixel power-on reset, the DINport receivedata from controller, the first pixel collect initial 24bit data then sent to the internal data latch, the other datawhichreshaping by the internal signal reshaping amplification circuit sent to the next cascade pixel through the DOport. Aftertransmission for each pixel, the signal to reduce 24bit. pixel adopt auto reshaping transmit technology, makingthepixelcascade number is not limited the signal transmission, only depend on the speed of signal transmission.

Features 

• The IC’s control circuit and the LED share the same power supply.
• Control circuit and RGB chip are integrated in a package of 3535 component, to form a complete external controlpixel.
• Built-in signal reshaping circuit, any pixel receives the signal, and then re-export after waveformreshapingtoensure that the waveform distortion of the circuit will not accumulate.
• Built-in Power-on reset and Power-off reset circuits.
• The three primary color of each pixel can achieve 256 level Gray scale, and to fulfill 16777216 colors full-colordisplay, its scan frequency is higher than 2KHz.
• The reception and decoding of cascading data can be completed by a Serial Interface.
• Any two transmission distance not more than 3 Meters, without adding any circuit.
• When the refresh rate is of 30fps, the cascade numbers are not less than 1024 pixels.
• Data transfer speeds up to 800Kbps.
• Highly brightness consistency, and cost-effective.
