Questions
How big is the PAS16DB PCB?
It measures 53.3 × 76.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PAS16DB use?
58 parts, built around the OPA1688ID, 1N4148W, GZ2012D601TF and SJ1-3535NG. 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 PAS16DB KiCad files?
From the demik/oldworld repository on GitHub, at the commit this page was made from: the board is EDA/NUBUSPAS16-DB/PAS16DB.kicad_pcb and its schematic EDA/68k-nano+/68000sbc.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PAS16DB design in my own project?
Its repository publishes it under the CERN-OHL-P-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).
