Questions
How big is the 27c322 PCB?
It measures 47 × 99.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 27c322 use?
11 parts, built around the MMBT3906. 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 27c322 KiCad files?
From the keirf/pcb-projects repository on GitHub, at the commit this page was made from: the board is 27c322-adaptor/27c322.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the 27c322 design in my own project?
Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
