Questions
How big is the Morse2Prototype PCB?
It measures 88.9 × 63.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Morse2Prototype use?
22 parts, built around the MAX7426EUA+ and SN74AHC74D. 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 Morse2Prototype KiCad files?
From the dolson14/k7arx repository on GitHub, at the commit this page was made from: the board is projects/Morse2Prototype/Morse2Prototype.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Morse2Prototype design in my own project?
Its repository states no licence, so its author keeps all rights: ask dolson14 before reusing the design.
