The WS2811 pixel protocol, developed by World Semi in China, is known for its benefits and versatility in a compact SOP package. While the WS2813 and other higher quality protocols are often preferred, the WS2811 remains a popular choice for pixel lighting displays. Its control circuit, which comes in a SOP8 package, allows for a greater range of LED options.

Our LED Strip Studio products support WS2811 as a pixel IC type. Let us help you with your pixel LED installation – get in touch for more information.
