Questions
What parts does the Stenography use?
52 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 Stenography KiCad files?
From the code2344/stenography repository on GitHub, at the commit this page was made from: the board is stenography.kicad_pcb and its schematic stenography.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Stenography design in my own project?
Its repository states no licence, so its author keeps all rights: ask code2344 before reusing the design.
