Questions
How big is the Controller Room PCB?
It measures 119 × 39 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Controller Room use?
79 parts, built around the ESP32-WROOM-32, MAX3485ED, RY8310 and EL817S1(C)(TU)-F. 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 Controller Room KiCad files?
From the crexodon/LED-Window-Matrix-Neo repository on GitHub, at the commit this page was made from: the board is Hardware/Controller_Room/Controller_Room.kicad_pcb and its schematic Hardware/Controller_Room/Controller_Room.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Controller Room design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
