Questions
How big is the Holes PCB?
It measures 36 × 1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Holes use?
17 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 Holes KiCad files?
From the isaacphi/holes2 repository on GitHub, at the commit this page was made from: the board is electrical/holes/holes.kicad_pcb and its schematic electrical/holes/holes.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Holes design in my own project?
Its repository states no licence, so its author keeps all rights: ask isaacphi before reusing the design.
