LED Pixel Protocol UCS9812

Overview

This pixel protocol was designed by Lianxinke in China. UCS9812 is equipped with all the same features as its previous version, UCS8903, but supports 4 RGB pixels off the one chip. The control circuit comes in a SOP16 package, allowing for more flexibility with LED choice.

Current Control

UCS9812 has the ability to digitally control the current of the connected LEDs. Use the 4-bit global current control to lower the brightness without sacrificing resolution. This global brightness control can be set when configuring your PixLite Mk3 controller.

Considerations for Use

Advantages

  • Up to 24V, allowing for very long cable lengths
  • High PWM rate allows for filming these pixels with cameras up to 35fps
  • 16 bits of data for each color makes dimming curves very smooth
  • Drives 4 pixels off a single SOP16 chip.

UCS9812 Disadvantages

  • Data-only restricts refresh rates to be limited by the speed of the protocol, which can be slow
  • No redundancy in data
