keyestudio 2812 shield adopts a 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.
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.
LED has the advantages of low driving voltage, environmental-friendly, energy saving, high brightness, large scattering angle, good consistency, long life span, etc.
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.
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.
