LED Pixel Protocol SM16511


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.

Considerations for Use


  • Up to 24V, allowing for very long cable lengths
  • High PWM rate allows for filming these pixels with cameras up to 100fps
  • Flexible PWM configuration
  • Option for white LED allows for higher brightness and more color mixing options


  • Data-only restricts refresh rates to be limited by the speed of the protocol, which can be slow
  • Only 8 bits of data for each color makes dimming curves less smooth
  • No redundancy in data
  • Operation relies on addressing of the pixels to be correct from the factory (See Operational Behavior below)

Operational Behavior

SM16511 will work with the generic DMX512 protocol as is, but this assumes correct factory set addressing of the individual pixels (addressing is usually pre-set at the factory in the pixels themselves, by using the external addressing line).

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.
