This pixel protocol was designed by Lianxinke in China. UCS1904 is an improved design of its previous version, UCS1903, operating up to 24V instead of 12V and using improved optics to achieve a higher PWM rate. The control circuit comes in a SOP8 package, allowing for more flexibility with LED choice.
Output Pixel Voltage
|5 - 24V|
|Up to 50fps|
Data Transfer Rate
|400 - 800kbps|
Redundant Data Line
Considerations for Use
- Up to 24V, allowing for very long cable lengths
- High PWM rate allows for filming these pixels with cameras up to 50fps
- 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
