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 into a 5050 SMD component.
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.
Specifications of Single LED:
- Anti-reverse protection circuit
- 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.
