Questions
How big is the Mod synth lpf PCB?
It measures 62.2 × 109.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mod synth lpf use?
42 parts, built around the LM13700M and BC558. 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 lpf KiCad files?
From the bobbarnes1981/mod_synth repository on GitHub, at the commit this page was made from: the board is mod_synth_lpf/schematic/mod_synth_lpf.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mod synth lpf design in my own project?
Its repository states no licence, so its author keeps all rights: ask bobbarnes1981 before reusing the design.
