Questions
How big is the Vent PCB?
It measures 99.1 × 99.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Vent use?
113 parts, built around the ATMEGA1284P-AU, CP2102N-A01-GQFN24, LMV358 and MAX3232ID. 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 Vent KiCad files?
From the pandemiaplan/OP-Vent repository on GitHub, at the commit this page was made from: the board is OPVentPCB_V2.2/SRC/Vent.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Vent design in my own project?
Its repository states no licence, so its author keeps all rights: ask pandemiaplan before reusing the design.
