Questions
How big is the Synth chipz klein vcf PCB?
It measures 45 × 22 mm and has 2 copper layers, 0.83 mm thick.
What parts does the Synth chipz klein vcf use?
57 parts. 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 Synth chipz klein vcf KiCad files?
From the CircuitMonkey/CHIPs repository on GitHub, at the commit this page was made from: the board is Synth/synth-chipz-klein-vcf/synth-chipz-klein-vcf.kicad_pcb and its schematic 0131-dcdc-3a/PCB-KiCAD/0131-dcdc-3a/0131-dcdc-3a.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Synth chipz klein vcf design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
