Questions

What parts does the Lm1875-v2 use?

27 parts, built around the LM1875T. 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 Lm1875-v2 KiCad files?

From the milinda/diyaudio repository on GitHub, at the commit this page was made from: the board is lm1875-v2/lm1875-v2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Lm1875-v2 design in my own project?

Its repository states no licence, so its author keeps all rights: ask milinda before reusing the design.
