Questions
How big is the Shortstack PCB?
It measures 125.3 × 71 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Shortstack use?
54 parts, built around the 1N4148W. 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 Shortstack KiCad files?
From the hazels-garage/shortstack repository on GitHub, at the commit this page was made from: the board is pcbs/shortstack.kicad_pcb and its schematic pcbs/shortstack.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Shortstack design in my own project?
Its repository publishes it under the CC-BY-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
