Questions
How big is the Mutsu PCB?
It measures 307 × 95.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mutsu use?
155 parts, built around the 1N4148WT. 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 Mutsu KiCad files?
From the SoanGlengan/Mutsu repository on GitHub, at the commit this page was made from: the board is Mutsu.kicad_pcb and its schematic Keyboard-2-backups/Keyboard-2-2025-08-15_204443/Keyboard-2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mutsu design in my own project?
Its repository states no licence, so its author keeps all rights: ask SoanGlengan before reusing the design.
