More Pixel Protocols

LED Pixel Protocol UCS9812


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


  • 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
