Overview
This pixel protocol was designed by Lianxinke in China. UCS8903 is very similar to UCS2903 but is built on a 16-bit color data design, which improves color resolution and dimming curves. Its PWM rate is slightly lower than the UCS29xx series, but still offers flicker-free footage on standard cameras. 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 34fps
- 16 bits of data for each color makes dimming curves very smooth
Disadvantages
- Data-only restricts refresh rates to be limited by the speed of the protocol, which can be slow
- No redundancy in data
