<br>
==Introduction==
keyestudio 2812 shield adopts stackable design, compatible with UNO board. It is an intelligent controlled LED light source that the control circuit and RGB chip are integrated in a 5050 SMD component. It includes intelligent digital port data latch and signal reshaping amplification drive circuit. 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.<br>
The data transfer protocol uses single NZR communication mode. After the pixel power-on reset, the DI port receives data from controller, the first pixel collect initial 24bit data then sent to the internal data latch.<br>
LED has the advantages of low driving voltage, environmental-friendly, energy saving, high brightness, large scattering angle, good consistency, long life span, etc. <br>

<br>

== Specification of Single LED  ==
* Anti-reverse protection circuit; the reverse power connection will not damage the internal IC of the LED. 
* IC control circuit and LED point light source use the same power supply. 
* Control circuit and the RGB chip are integrated into a 5050 SMD component, forming a complete control of pixel point. 
* 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. 
* Built-in power-on reset circuit and power-down reset circuit.
* 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.
* Serial cascade interface, to complete the reception and decoding of data via a signal line.
* When transmission distance between two arbitrary points is no more than five meters, no extra circuit needed. 
* When the refresh rate is 30fps, cascade number no less than 1024 points. 
* Data sending speed can reach 800Kbps.
* The color of the light is highly consistent, cost-effective.

<br>

== Advantages  ==
* LED with built-in IC is brighter than common LED
* High consistency of RGB chip inside all LEDs
* Built-in driver IC with reliable performance.
* Use hard plastic packaging, preventing press damage.

<br>

== Details ==
* '''Dimensions:''' 69mm x 57mm x 18mm
* '''Weight:''' 21.1g
