This pixel protocol was designed by OPSCO 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.
Are you looking for SK9822 pixel drivers that work with Art-Net or sACN? All PixLite Mk2 and Mk3 products support SK9822 as an available Pixel IC type, so get in touch with us to find out how the lighting specialists at Advatek can support you in your pixel lighting project.

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