This pixel protocol was designed by Sunmoon Microelectronics in China. SM16803 receives 8-bit data, but upscales this to a gamma-corrected 16-bit curve, giving the ability for high resolution, with fewer DMX channels required. The control circuit comes in a SOP8 package, allowing for more flexibility with LED choice.
Are you looking for SM16803 pixel drivers that work with Art-Net or sACN? All PixLite Mk2 and Mk3 products support SM16803 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.
SM16803 has the ability to digitally control the current of the connected LEDs. Use the 4-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
|Color Resolution||8 bits with 16-bit built-in gamma correction|
|Output Pixel Voltage||5 – 30V|
|Suitable Camera||Up to 133fps, see Refresh Rate and PWM Rate|
|Data Transfer Rate||800 kbps|
|Redundant Data Line||No|
- Very high PWM rate allows for filming these pixels with cameras up to 133fps
- Up to 30V, allowing for very long cable lengths
- 16-bit built-in gamma correction makes dimming curves more smooth
- Data-only restricts refresh rates to be limited by the speed of the protocol, which will generally be slow
- No redundancy in data
