TM1803 Advantages
- Up to 24V, allowing for very long cable lengths
TM1803 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
- Narrow tolerance for timing errors, making it less reliable than TM1804
