Questions
How big is the Buildbutton PCB?
It measures 40 × 40 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Buildbutton use?
9 parts, built around the IRLIZ44N. 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 Buildbutton KiCad files?
From the ayoy/kicad-projects repository on GitHub, at the commit this page was made from: the board is buildbutton/v1/buildbutton.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Buildbutton design in my own project?
Its repository states no licence, so its author keeps all rights: ask ayoy before reusing the design.
