Questions
How big is the Opamp PCB?
It measures 47.2 × 25.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Opamp use?
40 parts, built around the MMBT3904, SSW-101-02-S-S-RA and MMBT3906. 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 AlanD1967/opamp repository on GitHub, at the commit this page was made from: the board is untitled.kicad_pcb. 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 AlanD1967 before reusing the design.
