Overview
This pixel protocol was designed by Lianxinke in China. UCS2903 is an improved design of its previous version, UCS1904, offering a constant current design, allowing for a more stable lighting system. The control circuit comes in a SOP8 package, allowing for more flexibility with LED choice.

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 54fps
Disadvantages
- Data-only restricts refresh rates to be limited by the speed of the protocol, which can be slow
- Only 8 bits of data for each color makes dimming curves less smooth
- No redundancy in data
