Questions
How big is the OA 0x00 PCB?
It measures 160 × 50.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the OA 0x00 use?
206 parts. 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 OA 0x00 KiCad files?
From the EmilsSturitis/OA-opAmp-dev repository on GitHub, at the commit this page was made from: the board is HW/OA_0x00.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the OA 0x00 design in my own project?
Its repository states no licence, so its author keeps all rights: ask EmilsSturitis before reusing the design.
