Questions

How big is the Bau maus PCB?

It measures 73.8 × 66 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Bau maus use?

19 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 Bau maus KiCad files?

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

Can I use the Bau maus design in my own project?

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