Questions
How big is the ModuPad KICAD PCB?
It measures 65 × 95 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ModuPad KICAD use?
22 parts. 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 ModuPad KICAD KiCad files?
From the lassiipk/ModuPad repository on GitHub, at the commit this page was made from: the board is PCB/ModuPad_KICAD/ModuPad_KICAD.kicad_pcb and its schematic KiCad Libraries/XIAO Footprints/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 ModuPad KICAD design in my own project?
Its repository states no licence, so its author keeps all rights: ask lassiipk before reusing the design.
