Questions
How big is the Opamp PCB?
It measures 45.7 × 40.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Opamp use?
36 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 Opamp KiCad files?
From the mothdotmonster/random-pcbs repository on GitHub, at the commit this page was made from: the board is opamp/opamp.kicad_pcb and its schematic atx breakout/atx breakout.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Opamp design in my own project?
Its repository states no licence, so its author keeps all rights: ask mothdotmonster before reusing the design.
