Questions
How big is the Midirouter PCB?
It measures 153.5 × 49 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Midirouter use?
38 parts, built around the CMOD A7-35T and PN2222A. 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 Midirouter KiCad files?
From the tomarus/midirouter-kicad repository on GitHub, at the commit this page was made from: the board is kicad/backplane/midirouter.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Midirouter design in my own project?
Its repository states no licence, so its author keeps all rights: ask tomarus before reusing the design.
