WS2812B-MINI-X1

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 of 3535 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 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.
•  No need for external electric components and even the capacitor.
•  It won't be damaged even if the power supply reversed connected.

Applications

•  LED embedded illuminated keyboards and mice.
•  Full-color module, Full-color flexible strip.
•  LED decorative lighting, Indoor/outdoor LED video irregular screen.

General description
WS2812B-Mini-V3J 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. It also includes a high-precision internal oscillator and a programmable constant current control part to ensure
high color consistency.

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.

RESET time>280μs , it won't cause wrong reset while interruption, it supports the lower frequency and inexpensive MCU.

Refresh Frequency updates to 2KHz, Low Frame Frequency and No Flicker appear in HD Video Camera, it improve excellent display effect.

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 more simple circuit, small volume, convenient installation.
