UCS1903 Pixel LED Strip Lighting Display

The UCS1903 control circuit uses a data signal to control the color and brightness of each pixel. The data signal is transmitted along the LED strip, and each pixel reads the signal and adjusts its output accordingly. This allows for the creation of complex and dynamic lighting effects, including color fades, strobing, and other patterns.

UCS1903 Pixel LED Strips are typically sold in rolls, and can be cut to length to fit a specific application. They are often used in architectural lighting, advertising displays, and other applications where dynamic and precise control of color and brightness is required. They are also popular among hobbyists and DIY enthusiasts for creating custom lighting projects.

UCS1903 Pixel LED Strip Features

The UCS1903 light strip is an addressable LED light similar to the WS2811 and SM16703 LED tape light, and is commonly used for various lighting projects. It has the following features:

Intelligent Control:

The strip is driven by a UCS1903 chip, which is compatible with most LED controllers like SP series Bluetooth and Wifi controllers and the K-1000C and K-8000C programmable controllers. This chip is an external driver that allows for control of every 3 or 6 LEDs on the strip, enabling the creation of complex lighting effects and patterns.

Full Color RGB

The strip can produce a wide range of colors by mixing red, green, and blue LEDs. This allows for the creation of dynamic and colorful lighting displays.

Adhesive Backing

The strip comes with a 3M self-adhesive backing, which makes it easy to install in a variety of locations.

Flexible Design

The strip is flexible and can be bent or curved to fit around corners or other obstacles.

Waterproof Options

The strip is available in IP20, IP65, IP67, and IP68, making it suitable for both indoor and outdoor use.

High Brightness

The UCS1903 chip allows for the production of high-brightness LEDs, which makes the light strip suitable for a wide range of lighting applications, including decorative lighting, architectural lighting, and accent lighting.


The UCS1903 light strip can be programmed to display different colors, patterns, and effects. This makes it highly customizable and suitable for a wide range of creative applications.

Overall, the UCS1903 light strip is a versatile and powerful lighting solution that is ideal for a wide range of applications, including home lighting,

UCS1903 vs WS2811, What Is the Difference?

UCS1903 and WS2811 are two different types of LED driver ICs (integrated circuits) commonly used for controlling addressable LED strips. However, there are some key differences between them.

Transfer rate 

Another difference is the number of channels each IC supports. UCS1903 supports 3 channels (red, green, and blue) and has a maximum data transfer rate of 800 kbps. WS2811 also supports 3 channels but has a maximum data transfer rate of 400 kbps.


Considering the compatibility, both the WS2811 and UCS1903 are widely supported by LED controller boards and software. However, it’s important to note that they are not interchangeable. If your LED strip is designed for use with a WS2811 chip, you cannot use a UCS1903 chip to control it (and vice versa). 


In terms of usage, both UCS1903 and WS2811 are popular choices for LED strip lighting, pixel lighting, and other lighting applications. However, the specific choice of IC depends on the requirements of other components being used.

Overall, the choice between UCS1903 and WS2811 depends on your specific needs and preferences. If you prioritize ease of use and flexibility, the WS2811 may be a better choice. If you need reliability and robustness in challenging environments, the UCS1903 may be a better fit.
