LED Pixel Protocol UCS7604


This protocol was designed by Lianxinke in China. UCS7604 allows connection of either one RGB or one RGBW LED per chip, and selection between RGB/RGBW is made available through digital configuration. It has a resolution of 16-bit, and the control circuit comes in a SOP10 package, allowing for more flexibility with LED choice.

Current Control

UCS7604 has the ability to digitally control the current of the connected LEDs. Use the 4-bit current control per color to lower the brightness without sacrificing resolution, and tune the current of individual colors, allowing for more accurate color mixing. This individual current control can be set when configuring your PixLite Mk3 controller.

Considerations for Use


  • 16 bits of data for each color makes dimming curves very smooth
  • Very high PWM rate allows for filming these pixels with cameras up to 533fps
  • Up to 30V, allowing for very long cable lengths
  • Option for white LED allows for higher brightness and more color mixing options


  • Data-only restricts refresh rates to be limited by the speed of the protocol, which can be slow
