From the project

RP2040-based USB DMX dongle with integrated web server

The rp2040-dmxsun is a multi-purpose DMX-512-A toolbox to control stage lighting systems. It's most common use-case is to transmit the DMX data generated on a PC, Raspberry Pi or similar in a format that the lighting fixtures on stage can understand. In the most simple case, it's an USB-DMX interface.

DMX-512-A works in networks called universes and each universe can contain up to 512 slots of data. dmxsun can transmit up to 16 universes, meaning you can control 8192 slots of DMX data at the same time.
