Questions
How big is the MorsePrototype PCB?
It measures 65 × 51 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MorsePrototype use?
50 parts, built around the LT1763CDE, SN74AHC1G32DBV and TS5A2066YZP. 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 MorsePrototype KiCad files?
From the dolson14/k7arx repository on GitHub, at the commit this page was made from: the board is projects/MorsePrototype/MorsePrototype.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the MorsePrototype design in my own project?
Its repository states no licence, so its author keeps all rights: ask dolson14 before reusing the design.
