README
README.mdTrance
Live Lighting control via Wifi.
USB-DMX
This is a Trance-Controller that can be plugged into Eurolite Quick-DMX USB ports. With this there is no need to power the Controller.
Software
To ensure a flexible and easy software, there is a Arduino library, that implements the communication side of the software. By updating this Library with more Protocols or more reliable networking, we can expand the functionallity of every trance controller, despite different hardware.
Vision
- Centralized Provision and setup of trance-family controllers. Inspired by Unifi or Node red.
- Integration with popular open and propriatary smart home systems.

Questions
How big is the Usb dmx PCB?
It measures 44 × 20 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Usb dmx use?
21 parts, built around the ESP32-S3-MINI-1U-N8, MAX485ED, AMS1117-3.3 and USBLC6-2SC6. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Usb dmx KiCad files?
From the Soraxem/trance repository on GitHub, at the commit this page was made from: the board is usb-dmx/pcb/usb-dmx.kicad_pcb and its schematic devboard/pcb/devboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Usb dmx design in my own project?
Its repository publishes it under the CERN-OHL-P-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
