Questions
How big is the Punbox PCB?
It measures 53 × 54.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Punbox 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 Punbox KiCad files?
From the RyanDraves/nlb repository on GitHub, at the commit this page was made from: the board is emb/project/punbox/hw/punbox.kicad_pcb and its schematic emb/project/punbox/hw/punbox.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Punbox design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
