Questions
How big is the Lfo PCB?
It measures 39.6 × 99.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Lfo use?
52 parts, built around the LM324. 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 Lfo KiCad files?
From the blthree/synth_schematics repository on GitHub, at the commit this page was made from: the board is lfo/lfo.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lfo design in my own project?
Its repository states no licence, so its author keeps all rights: ask blthree before reusing the design.
