Pixel Protocol Overview: HD108

Building upon the expansive feature set of HD107S, HD108 boasts an even more impressive design, featuring 16 bit operation and a higher PWM rate. The control circuit and LEDs are integrated in a 5050 SMD package, which provides a small physical footprint for each pixel.

PixLite Support

Are you looking for HD108 pixel drivers that work with Art-Net or sACN? All PixLite Mk3 products support HD108 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

HD108 has the ability to digitally control the current of the connected LEDs. Use the 5-bit current control per color to lower the brightness without sacrificing resolution, and tune the current of individual colors, allowing for more accurate color mixing. This individual current control can be set when configuring your PixLite Mk3 controller
