Pixel Protocol Overview: HD107S

This pixel protocol was designed by Hida Optoelectronics in China, who use the 107S chip by Newstar LED. Very similar to the APA range, HD107S boasts everything APA102 brings, with a higher PWM rate and brighter LEDs. 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 HD107S pixel drivers that work with Art-Net or sACN? All PixLite Mk1 and Mk2 products support HD107S 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.

Note: when you used HD107S LEDs, select ‘APA102′ as your Pixel IC Type. This is the equivalent protocol that will allow you to use HD107S pixels.

HD107S Advantages

Presence of a clock allows for faster refresh rates
High PWM rate allows for filming these pixels with cameras up to 87fps

HD107S 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
