Questions
How big is the OPAmp PCB?
It measures 94.4 × 80.1 mm and has 2 copper layers, 1.62 mm thick.
What parts does the OPAmp use?
24 parts, built around the TIP120 and TIP125. 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 emibarg/OPAmp repository on GitHub, at the commit this page was made from: the board is OPAmp.kicad_pcb and its schematic OPAmp.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 emibarg before reusing the design.
