Questions
How big is the VCF1 rev1 PCB?
It measures 100 × 95 mm and has 4 copper layers, 4.69 mm thick.
What parts does the VCF1 rev1 use?
201 parts, built around the LM13700M and 74HC4053D. 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 VCF1 rev1 KiCad files?
From the ModularMayhem/mmm repository on GitHub, at the commit this page was made from: the board is VCF1_rev1/KiCad/VCF1_rev1.kicad_pcb and its schematic VCF1_rev1/KiCad/Audiopanel.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the VCF1 rev1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask ModularMayhem before reusing the design.
