Questions
What parts does the FirstPCB use?
19 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 FirstPCB KiCad files?
From the rossw42/keyboard_stuff repository on GitHub, at the commit this page was made from: the board is keyboards/FirstPCB/FirstPCB.kicad_pcb and its schematic keyboards/FirstPCB/FirstPCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the FirstPCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask rossw42 before reusing the design.
