Questions
How big is the Mod synth perc PCB?
It measures 41.9 × 109.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mod synth perc use?
48 parts, built around the TL072. 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 Mod synth perc KiCad files?
From the bobbarnes1981/mod_synth repository on GitHub, at the commit this page was made from: the board is mod_synth_perc/schematic/mod_synth_perc.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mod synth perc design in my own project?
Its repository states no licence, so its author keeps all rights: ask bobbarnes1981 before reusing the design.
