Questions
How big is the MainController PCB?
It measures 120 × 74.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MainController use?
44 parts, built around the 74LS125DC, LME78_05-1.0, MAX3232ID and LTV-817. 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 MainController KiCad files?
From the stefanhepp/fancylights repository on GitHub, at the commit this page was made from: the board is kicad/MainController/MainController.kicad_pcb and its schematic kicad/FancyController/FancyController.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MainController design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
