This pixel protocol was designed by Sunmoon Microelectronics in China. It uses a non-differential DMX512 protocol to drive pixel chips. The PWM rate is 3300Hz by default but can be configured to run at 800Hz if desired. The control circuit can come in a SOP10/SOP16 package, depending on which functions are being used, allowing for more flexibility with LED choice.
PixLite Support
Are you looking for SM16511 pixel drivers that work with Art-Net or sACN? All PixLite Mk2 and Mk3 products support SM16511 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 configuring your PixLite device, select 'DMX512' as your Pixel Type. This is the equivalent protocol that will allow you to use SM16511 pixels.
