Questions
How big is the DB9 Serial Expansion Card Rev2 PCB?
It measures 30.8 × 36.5 mm and has 2 copper layers, 0.8 mm thick.
What parts does the DB9 Serial Expansion Card Rev2 use?
27 parts, built around the FT231XS-R. 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 DB9 Serial Expansion Card Rev2 KiCad files?
From the jyancat/Serial-Expansion-Card repository on GitHub, at the commit this page was made from: the board is Hardware/DB9 Serial Expansion Card Rev2.kicad_pcb and its schematic Hardware/DB9 Serial Expansion Card Rev2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DB9 Serial Expansion Card Rev2 design in my own project?
Its repository publishes it under the CERN-OHL-S-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).
