Questions
How big is the Mun PCB?
It measures 325.5 × 240.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mun use?
448 parts, built around the STM32F303CCT6, AT42QT2120-XU, WS2812B and GG0402052R542P. 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 Mun KiCad files?
From the RGBKB/Keyboard-files repository on GitHub, at the commit this page was made from: the board is Mun/Mun design files/Mun.kicad_pcb and its schematic BANANA/10133-04 Kicad Project/10133.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mun 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).
