Questions
How big is the Diymetro PCB?
It measures 162.8 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Diymetro use?
115 parts, built around the ATMEGA328P-PU, TL072, 74HC4051 and MMBT2222A. 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 Diymetro KiCad files?
From the tomarus/diymetro repository on GitHub, at the commit this page was made from: the board is kicad/diymetro/diymetro.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Diymetro design in my own project?
Its repository states no licence, so its author keeps all rights: ask tomarus before reusing the design.
