Questions
How big is the Lfk17 PCB?
It measures 74.3 × 99.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Lfk17 use?
148 parts, built around the AT90USB1286-AU. 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 Lfk17 KiCad files?
From the lfkeyboards/lfk17 repository on GitHub, at the commit this page was made from: the board is RevB/lfk17.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lfk17 design in my own project?
Its repository states no licence, so its author keeps all rights: ask lfkeyboards before reusing the design.
