WS2812 Shield 5*8 40-Bit 5050 Full-color LED Module Expansion Board

2812 shield adopts stackable design, compatible with UNOR3 board. 

It is an intelligent controlled LED light source that the control circuit and RGB chip are integrated into a 5050 SMD component. 

Each pixel interior not only includes intelligent digital port data latch and signal reshaping amplification drive circuit, but also includes a precision internal oscillator and a 12V programmable constant current control part, effectively ensuring the highly consistency of the pixel point light color.

The data transfer protocol uses single RZ (return-to-zero) communication mode. After the pixel power-on to reset, the DI port receives data from controller, the first 24bit data is extracted by the first pixel,and then sent to the data latch inside the pixel. 

LED has the advantages of low driving voltage, environmental-friendly, energy saving, high brightness, large scattering angle, good consistency, long life span, etc. 

1. Anti-reverse protection circuit; the reverse power connection will not damage the internal IC of the LED. 

2. IC control circuit and LED point light source use the same power supply. 

3. Control circuit and the RGB chip are integrated into a 5050 SMD component, forming a complete control of pixel point. 

4. Built-in signal reshaping circuit; signals received will be wave-reshaped first and then output to the next driver, ensuring wave-form distortion not accumulate. 

5. Built-in power-on reset circuit and power-down reset circuit.

6. Each pixel of the three primary color can achieve 256 brightness display; complete full color display of 16777216 colors; scan frequency no less than 400Hz/s.

7. Serial cascade interface, to complete the reception and decoding of data via a signal line.

8. When transmission distance between two arbitrary points is no more than five meters, no extra circuit needed. 

9. When the refresh rate is 30fps, cascade number no less than 1024 points. 

10. Data sending speed can reach 800Kbps.

11. The color of the light is highly consistent, cost-effective.

1. LED with built-in IC is brighter than common LED

2. High consistency of RGB chip inside all LEDs

3. Reliable performance of built-in driver IC

4. Use hard plastic packaging, preventing press damage.
