Questions
How big is the Dog dev PCB?
It measures 71 × 56 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Dog dev use?
16 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 Dog dev KiCad files?
From the PT233/dog_dev repository on GitHub, at the commit this page was made from: the board is circuit/circuit.kicad_pcb and its schematic circuit/circuit.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dog dev design in my own project?
Its repository states no licence, so its author keeps all rights: ask PT233 before reusing the design.
