Questions
How big is the DialPad PCB?
It measures 100 × 92 mm and has 2 copper layers, 1.6 mm thick.
What parts does the DialPad use?
21 parts, built around the 1N4148W. 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 DialPad KiCad files?
From the felixwittwer/DialPad repository on GitHub, at the commit this page was made from: the board is pcb/dialpad.kicad_pcb and its schematic pcb/OPL_Kicad_Library-master/Grove Vision AI V2 Library/Grove - Vision AI Module V2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DialPad design in my own project?
Its repository states no licence, so its author keeps all rights: ask felixwittwer before reusing the design.
