Questions
How big is the HAM Key PCB?
It measures 61 × 60.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the HAM Key use?
44 parts, built around the 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 HAM Key KiCad files?
From the HAM-Key/Lite-layout repository on GitHub, at the commit this page was made from: the board is HAM-Key.kicad_pcb and its schematic HAM-Key.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the HAM Key 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).
