Questions
How big is the KM54ALC PCB?
It measures 347.8 × 97.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the KM54ALC use?
172 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 KM54ALC KiCad files?
From the robin15/pcb repository on GitHub, at the commit this page was made from: the board is KM54ALC/KM54ALC.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the KM54ALC design in my own project?
Its repository states no licence, so its author keeps all rights: ask robin15 before reusing the design.
