The UCS1903 60leds/m Pixel LED Strip is a special type that we customized for our client, since the PCB is 17MM width and it has to be waterproof IP67 with silicone tube. So we not only customized the DC5V 17MM PCB, but also the 20mm width silicone tube. We revised the design several times, and finally the finished product works very well.  

The UCS1903 is a 3-channel LED display driver / controller with a built-in MCU digital interface, data latches and LED high voltage driving functions. It features superior performances and reliable functions. Under the control of the external MCU, it performs independent grayscale control through data-cascading transfer for driving large outdoor colour dot-matrix LED panels.
