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
