Questions
How big is the InputBoard PCB?
It measures 39.7 × 28.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the InputBoard use?
15 parts, built around the ATTINY814-SSN. 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 InputBoard KiCad files?
From the synthesissolutions/geeksforkids repository on GitHub, at the commit this page was made from: the board is hardware/!Archive/InputBoard/InputBoard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the InputBoard design in my own project?
Its repository states no licence, so its author keeps all rights: ask synthesissolutions before reusing the design.
