UCS1903 Advantages
- Up to 12V, allowing for long cable lengths
UCS1903 Disadvantages
- Low PWM rate makes theses pixels unsuitable for cameras
- 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
