Overview
This pixel protocol was designed by World Semi in China. WS2811 offers many of the benefits the WS28xx series is famous for, in a form factor of a SOP package. Typically, users will choose WS2813 or above for higher quality, however WS2811 is still one of the most common protocols for pixel lighting displays. The control circuit comes in a SOP8 package, allowing for more flexibility with LED choice.

Considerations for Use
Advantages
- Up to 12V, allowing for long cable lengths
Disadvantages
- Data-only restricts refresh rates to be limited by the speed of the protocol, which can be slow
- Low PWM rate makes theses pixels unsuitable for cameras
- Only 8 bits of data for each color makes dimming curves less smooth
- No redundancy in data
