This pixel protocol was designed by APA Electronic Co. in Taiwan. Also known as “Superled”, APA102C 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. Very similar to its previous version, APA102, APA102C provides a larger metallic area for better heat dissipation.
PixLite Support
Are you looking for APA102C pixel drivers that work with Art-Net or sACN? All PixLite Mk1, Mk2, and Mk3 products support APA102C 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.
Current Control
APA102C 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

APA102C Advantages
- Presence of a clock allows for faster refresh rates
- High PWM rate allows for filming these pixels with cameras up to 64fps
- Dissipates heat more efficiently than APA102
APA102C 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
