A DMX controller under 5€ that works as an Enttec Open DMX USB (73€ on Thomman)
Based on https://diyprojects.tech/2013/05/diy-usb-dmx-dongle-interface-for-under-10/

This case has been designed to be as slim as possible.

It only needs a XLR/DMX plug and a RS485 adapter that uses an FTDI RS232 Serial Chip.
