Questions
How big is the MiniWAV PCB?
It measures 50.8 × 22.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MiniWAV use?
23 parts. 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 MiniWAV KiCad files?
From the DepartmentOfAlchemy/MiniWAV repository on GitHub, at the commit this page was made from: the board is board/MiniWAV/MiniWAV.kicad_pcb and its schematic board/MiniWAV/MiniWAV.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MiniWAV design in my own project?
Its repository states no licence, so its author keeps all rights: ask DepartmentOfAlchemy before reusing the design.
