Questions
How big is the Fauxkey PCB?
It measures 58.5 × 26.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Fauxkey use?
17 parts, built around the E73-2G4M08S1C and LTC4054ES5-4.2#PBF. 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 Fauxkey KiCad files?
From the jmgao/fauxkey repository on GitHub, at the commit this page was made from: the board is pcb/fauxkey.kicad_pcb and its schematic pcb/fauxkey.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Fauxkey design in my own project?
Its repository states no licence, so its author keeps all rights: ask jmgao before reusing the design.
