Overview
This pixel protocol was designed by APA Electronic Co. in Taiwan. Also known as “Superled”, APA102 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.
APA102C uses the same protocol, but provides a larger metallic area for better heat dissipation.
Current Control
APA102 has the ability to digitally control the current of the connected LEDs. Use the 5-bit global current control to lower the brightness without sacrificing resolution. This global brightness control can be set when configuring your PixLite Mk3 controller.

Considerations for Use
Advantages
- Presence of a clock allows for faster refresh rates
- High PWM rate allows for filming these pixels with cameras up to 64fps
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
