Questions
How big is the DMH VCF Diode Ladder PCB PCB?
It measures 96 × 157.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the DMH VCF Diode Ladder PCB use?
68 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 DMH VCF Diode Ladder PCB KiCad files?
From the DeMarco/DMH-VCF-Diode-Ladder repository on GitHub, at the commit this page was made from: the board is DMH_VCF_Diode_Ladder_PCB/DMH_VCF_Diode_Ladder_PCB.kicad_pcb and its schematic DMH_VCF_Diode_Ladder_PANEL/DMH_VCF_Diode_Ladder_PANEL.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DMH VCF Diode Ladder PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask DeMarco before reusing the design.
