WS2812B-Mini is an intelligent control LED light source that the control circuit and RGB chip are integrated in a
package of 3535 component. 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 current 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 first pixel collect initial 24bit data then sent to the internal data latch, the other data
which reshaping by the internal signal reshaping amplification circuit sent to the next cascade pixel through the DO
port. After transmission for each pixel, the signal to reduce 24bit. pixel adopt auto reshaping transmit technology,
making the pixel cascade number is not limited the signal transmission, only depend on 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 moresimplecircuit, small volume, convenient installation.

Features and Benefits
The IC’s control circuit and the LED share the same power supply.
Control circuit and RGB chip are integrated in a package component, to form a complete external control
pixel.
Built-in signal reshaping circuit, any pixel receives the signal, and then re-export after waveform reshaping to
ensure 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-color
display, its scan frequency is higher than 400Hz/s.
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 of 30fps, cascade numbers are not less than 1024 points.
Data transfer speeds up to 800Kbps. Highly brightness consistency, and cost-effective. - Applications
Full-color module, Full-color flexible strip.
LED decorative lighting, Indoor/outdoor LED video irregular screen.
