Questions
How big is the Minidisc PCB?
It measures 96 × 78 mm and has 4 copper layers, 0.8 mm thick.
What parts does the Minidisc use?
145 parts, built around the F1C200S, CH340E, GD25D05CTIGR and TF-015. 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 Minidisc KiCad files?
From the befinitiv/minidisc_cad repository on GitHub, at the commit this page was made from: the board is pcb/minidisc.kicad_pcb and its schematic pcb/buttons.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Minidisc design in my own project?
Its repository states no licence, so its author keeps all rights: ask befinitiv before reusing the design.
