Questions
How big is the Air75 PCB?
It measures 78.7 × 58.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Air75 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 Air75 KiCad files?
From the ikrishagarwal/Air75 repository on GitHub, at the commit this page was made from: the board is PCB/Air75.kicad_pcb and its schematic PCB/Air75.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Air75 design in my own project?
Its repository states no licence, so its author keeps all rights: ask ikrishagarwal before reusing the design.
