Overview
This pixel protocol was designed by Titan Micro Electronics in China. It is an improved design of its previous version, TM1804, but offers a redundant data line to allow a continuous data path even if a single pixel fails. The control circuit comes in a SOP10 package, allowing for more flexibility with LED choice.

Considerations for Use
Advantages
- Up to 24V, allowing for very long cable lengths
- Redundant data line reduces chance of entire strip failure
Disadvantages
- Data-only restricts refresh rates to be limited by the speed of the protocol, which can be slow
- Low PWM rate only allows for filming these pixels with cameras up to 23fps
- Only 8 bits of data for each color makes dimming curves less smooth
