Overview
This pixel protocol was designed by OPSCO in China. The control circuit and LEDs are integrated in a 5050 SMD package, which provides a small physical footprint for each pixel.
SK6851 is designed to be integrated in series with a higher voltage than standard 5V pixel LEDs, using a 4V input voltage level. Instead of a typical 24V design requiring groups of six LEDs connected to each pixel IC, a typical SK6851 circuit places six pixel ICs in series on a 24V DC circuit, allowing for individual pixel control at 24V.
Note: Advatek Lighting is in no way affiliated with OPSCO.

Considerations for Use
Advantages
- 24V power design, allows for long cable lengths and long chains of pixels with high pixel density
- High PWM rate allows for filming these pixels with cameras up to 133fps
Disadvantages
- Data-only restricts refresh rates to be limited by the speed of the protocol, which can be slow
- Only 8 bits of data for each color makes dimming curves less smooth
- No redundancy in data
