Pixel Protocol Overview: SK6822

This pixel protocol was designed by OPSCO in China. This simple pixel protocol offers quality at an affordable price, which is why SK6822 is one of the most common protocols for pixel lighting displays. It offers all the same features as its RGBW version, SK6818, but is dedicated to RGB and also offers a backup data line for redundancy in case of a chip failure. The control circuit and LEDs are integrated in a 5050 SMD package, which provides a small physical footprint for each pixel.

SK6822 Advantages

  • High PWM rate allows for filming these pixels with cameras up to 40fps
  • Redundant data line reduces chance of entire strip failure

SK6822 Disadvantages

  • Data-only restricts refresh rates to be limited by the speed of the protocol, which will generally be slow
  • Only 8 bits of data for each color makes dimming curves less smooth
  • Limited to 5V, causing short cable lengths
