Questions
How big is the Keyboardv2 PCB?
It measures 112 × 45.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Keyboardv2 use?
44 parts, built around the 74HC595. 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 Keyboardv2 KiCad files?
From the dojoe/keyboardv2 repository on GitHub, at the commit this page was made from: the board is hw/keyboardv2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Keyboardv2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask dojoe before reusing the design.
