Questions
What parts does the Simple OpAmp use?
174 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 Simple OpAmp KiCad files?
From the mwwhited/EmbeddedBakery repository on GitHub, at the commit this page was made from: the board is circuits/AnalogCalculator/SimpleOpAmp/Simple OpAmp/Simple OpAmp.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Simple OpAmp design in my own project?
Its repository states no licence, so its author keeps all rights: ask mwwhited before reusing the design.
