Questions
How big is the Falsus6 PCB?
It measures 155.7 × 55.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Falsus6 use?
43 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 Falsus6 KiCad files?
From the harrfry/falsus6 repository on GitHub, at the commit this page was made from: the board is falsus6.kicad_pcb and its schematic falsus6.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Falsus6 design in my own project?
Its repository states no licence, so its author keeps all rights: ask harrfry before reusing the design.
