Introduction

keyestudio 2812 shield adopts stackable design compatible with UNO board. It is an intelligent control 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 with 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 of power supply will not damage the internal IC of the LED.
  • IC control circuit and LED point light source uses the same power supply.
  • control circuit and the RGB chip are integrated in 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 to 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, completed 16777216 color full color display, scan frequency no less than 400Hz/s
  • Serial cascade interface, via a signal line to complete the reception and decoding of data.
  • 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 chips for all LEDs
  • Reliable performance of built-in driver IC
  • Use hard plastic for packaging, prevent press damage
