Overview
This pixel protocol was designed by Titan Micro Electronics in China. TM1804 is equipped with all the same features as its previous version, TM1803, but uses a different data timing method to achieve a wider tolerance for inaccuracies, decreasing the chance of a bit error. 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
- Wider tolerance for timing errors, making it more reliable than 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 can be slow
- Only 8 bits of data for each color makes dimming curves less smooth
- No redundancy in data
