Keyestudio SK6812 5050 40Bits LED Shield For Arduino UNO R3

keyestudio SK6812 shield is particularly designed for Arduino controllers. Simply stack the shield onto UNO board to use.
The 40 SK6812 LEDs are all controlled by D13 pin on UNO board. When using, connect other components to the female headers of 2.54mm pitch, controlled by UNO board.
SK6812 LED is an intelligent controlled LED light source that integrates the control circuit and light-emitting circuit.

Each LED shape is as same as a 5050LED bead. Each element is a pixel. 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. After being amplified by the internal shaping processing circuit, the remaining data will be forwarded to the next cascade pixel point through the DO port of the LED.
The signal will be reduced by 24bit for each pixel point transmission.
The automatic shaping and forwarding technology is adopted for the pixel points, so that the cascade number of the pixel points is not limited by the signal transmission, and only limited by the signal transmission speed requirement.

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