UCS1904 IC Componenets

Short Description:

This pixel protocol was designed by Lianxinke in China. UCS1904 is an improved design of its previous version, UCS1903, operating up to 24V instead of 12V and using improved optics to achieve a higher PWM rate. The control circuit comes in a SOP8 package, allowing for more flexibility with LED choice.

UCS1904 Advantages

UCS1904 Disadvantages

  • 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
