Questions
How big is the OpAmpDevBoardProject PCB?
It measures 257 × 210 mm and has 4 copper layers, 5.72 mm thick.
What parts does the OpAmpDevBoardProject use?
113 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 OpAmpDevBoardProject KiCad files?
From the Gehtschon/OpAmpDevBoard repository on GitHub, at the commit this page was made from: the board is OpAmpDevBoardProject/OpAmpDevBoardProject.kicad_pcb and its schematic OpAmpDevBoardProject/OpAmpDevBoardProject.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the OpAmpDevBoardProject design in my own project?
Its repository publishes it under the CERN-OHL-S-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
