UCS2904 LED Strip

UCS2904 pixel protocol was designed by Lianxinke in China. UCS2904 offers all the same features as its RGB version, UCS2903, but is dedicated to RGBW. The control circuit comes in a SOP8 package, allowing for more flexibility with LED choice.

UCS2904 LED strip greyscale is 256, PWM is 1800Hz , voltage can be DC5v DC12v and DC24v. 

The UCS2904 RGBW LED strip is a 4-channel LED strip, which allows for control of red, green, blue, and white LEDs. With precise control of each group of LEDs (3LEDs 12v or 6LEDs 24v), the UCS2904 RGBW LED strip allows for dynamic and customizable lighting effects. UCS2904 LED strip offers high quality, versatility and customization for residential or commercial LED lighting projects.
