Pixel Protocol Overview: TM1804

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.

TM1804 Advantages

  • Up to 24V, allowing for very long cable lengths
  • Wider tolerance for timing errors, making it more reliable than TM1803

TM1804 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
