Questions
How big is the Controller Window PCB?
It measures 44.9 × 31.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Controller Window use?
28 parts, built around the MAX485ED, WS2811, L7805 and AO3400A. 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 Window 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_Window/Controller_Window.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 Window 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).
