Questions
How big is the MS20-VCF PCB?
It measures 207 × 128.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MS20-VCF use?
113 parts, built around the LM13700M, TL072 and BC559. 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 MS20-VCF KiCad files?
From the BleepSound/ms20-vcf-double repository on GitHub, at the commit this page was made from: the board is kicad-global/MS20-VCF.kicad_pcb and its schematic kicad-global/Filtre2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MS20-VCF design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
