Questions
How big is the Pskeeb PCB?
It measures 136.5 × 99.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pskeeb use?
29 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 Pskeeb KiCad files?
From the klesh/pskeeb repository on GitHub, at the commit this page was made from: the board is pskeeb1_gateron_ks27/pcbs/pskeeb.kicad_pcb and its schematic pskeeb1_gateron_ks27/pcbs/pskeeb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pskeeb design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
