Overview
This pixel protocol was designed by World Semi in China. WS2812B offers many of the benefits the WS28xx series is famous for. Typically, users will choose WS2813 or above for higher quality, however WS2812B is still one of the most common protocols for pixel lighting displays. While very similar to its previous version, WS2812, WS2812B offers reverse polarity protection on its power input, and also uses a 4-legged 5050 package, rather than 6. The control circuit and LEDs are integrated in a 5050 SMD package, which provides a small physical footprint for each pixel.

Considerations for Use
Advantages
- Up to 12V, allowing for long cable lengths
- Reverse polarity protection, making it more reliable than WS2812
- Only 4 legs, reducing chance of accidental shorts and making it more flexible than WS2812
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
