Questions
How big is the Lopill PCB?
It measures 23 × 59.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Lopill use?
34 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 Lopill KiCad files?
From the spbnick/lopill repository on GitHub, at the commit this page was made from: the board is lopill.kicad/lopill.kicad_pcb and its schematic lopill.kicad/lopill.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lopill design in my own project?
Its repository states no licence, so its author keeps all rights: ask spbnick before reusing the design.
