This pixel protocol was designed by Newstar in China. It is an improved design of its previous version, SK6822, using a clock line to achieve faster refresh rates and improved optics to achieve a higher PWM rate, which is why SK9822 is one of the most common protocols for pixel lighting displays. The control circuit and LEDs are integrated in a 5050 SMD package, which provides a small physical footprint for each pixel. similar type have APA102 APA102C APA107 HD107S.

SK9822 Advantages
- Presence of a clock allows for faster refresh rates
- Very high PWM rate allows for filming these pixels with cameras up to 154fps
SK9822 Disadvantages
- Only 8 bits of data for each color makes dimming curves less smooth
- Limited to 5V, causing short cable lengths
- No redundancy in data
