Questions
How big is the HAMKey One PCB?
It measures 53.4 × 53.9 mm and has 2 copper layers, 1.2 mm thick.
What parts does the HAMKey One use?
62 parts, built around the ME6210A33M3G, SLM6400 and DTC143Z. 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 HAMKey One KiCad files?
From the HAM-Key/One-layout repository on GitHub, at the commit this page was made from: the board is HAMKey-One.kicad_pcb and its schematic HAMKey-One.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the HAMKey One design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
