Questions
How big is the Lily58 Pro PCB?
It measures 142.5 × 106.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Lily58 Pro use?
87 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 Lily58 Pro KiCad files?
From the rek/keyboards repository on GitHub, at the commit this page was made from: the board is 06 - lilly58/pcb/Lily58_Pro.kicad_pcb and its schematic 02/pcb-left-v2/pcb-2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lily58 Pro design in my own project?
Its repository states no licence, so its author keeps all rights: ask rek before reusing the design.
