Pixel LED driver
MADRIX NEBULA is a two-output pixel driver that converts lighting data received via Art-Net, sACN or USB into an SPI signal to drive digital LED pixels directly.
Authorized dealer and solution partner
NEBULA is a small box that converts lighting data received over the network into the SPI signal digital LEDs understand. The effect designed in MADRIX 5 reaches NEBULA as Art-Net or sACN; the device passes this data pixel by pixel to strips and luminaires through its two ports. No separate converter is needed in between.
Anywhere there are pixel-controlled linear luminaires, LED strips and media mesh surfaces: in bridge and facade lighting, interior ceilings, shop windows, stage and event sets. 2,040 RGB pixels per device; with a luminaire of 8 pixels per meter, a line of about 255 meters can be managed with a single NEBULA.
We explain the difference between SPI and DMX512 in our SPI pixel control guide, and license and hardware selection in our MADRIX guide.
Highlights
All common ICs such as WS2811, WS2815, SK6812 and APA102 are supported; the protocol is selected separately for each port.
High data rate with clocked ICs; smooth imagery even on long pixel runs.
Devices are connected in series with two RJ45 ports; no separate switch port is needed for each device.
With ArtSync support, all ports and devices are updated in the same frame; no shifting or tearing in the image.
Can be powered from the 5–24 V DC screw terminal, from USB or from the LED line itself.
Fits a 35 mm DIN rail and can also be fixed to a wall with the two brackets in the box. The housing is insulating, flame class V-0.
Settings are made from the browser; the list of supported ICs grows with firmware updates.
5-year limited manufacturer warranty; average failure and return rate 0.09% (MADRIX, August 2025).

If you can't find the answer to your question, write to our technical team; let's evaluate it together for your project.
With firmware 6.00 and above, each of the two ports drives 1,020 RGB or 768 RGBW pixels; in total that is 2,040 RGB pixels, or 12 DMX universes, per device. On larger surfaces, several NEBULA units are daisy-chained over Ethernet.
It supports more than 70 SPI ICs such as WS2811, WS2812B, WS2815, SK6812 and APA102. You can look up the IC of the strip or luminaire in your project in the list above; if it is not listed, write to us.
No. NEBULA complies with the Art-Net and sACN standards and receives data from any compatible software, console or player. When used with MADRIX 5, it also offers conveniences such as the USB connection and sync mode.
Since its protection rating is IP20, in outdoor projects it is installed on a DIN rail inside a waterproof panel. Positioning the panel close to the luminaires keeps the SPI line short.
With firmware 6.00, capacity increased from 8 to 12 universes. The update is free and is done with the MADRIX HARDWARE MANAGER software.
