Questions

How big is the Auxi PCB?

It measures 110 × 140 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Auxi use?

49 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 Auxi KiCad files?

From the cesaraz455/auxi repository on GitHub, at the commit this page was made from: the board is auxi.kicad_pcb and its schematic auxi.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Auxi design in my own project?

Its repository states no licence, so its author keeps all rights: ask cesaraz455 before reusing the design.
