Questions

How big is the Guitar waveform proj PCB?

It measures 50.5 × 102 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Guitar waveform proj use?

40 parts, built around the LM324, NMJ6HFD2-AU and TP0604N3-G. 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 Guitar waveform proj KiCad files?

From the HDEmerald/waveform_viewer repository on GitHub, at the commit this page was made from: the board is pcb/Guitar_waveform_proj.kicad_pcb and its schematic pcb/Guitar_waveform_proj.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Guitar waveform proj design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
