UCS2904 Advantages
- Up to 24V, allowing for very long cable lengths
- High PWM rate allows for filming these pixels with cameras up to 60fps
- Presence of white LED allows for higher brightness and more color mixing options
UCS2904 Disadvantages
- Data-only restricts refresh rates to be limited by the speed of the protocol, which will generally be slow
- Only 8 bits of data for each color makes dimming curves less smooth
- No redundancy in data
