Questions
How big is the DMH VCEG PCB 1 Mk1 1 PCB?
It measures 148 × 175 mm and has 2 copper layers, 1.6 mm thick.
What parts does the DMH VCEG PCB 1 Mk1 1 use?
241 parts, built around the CD4066BE, BC548, BC558 and SB140. 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 VCEG PCB 1 Mk1 1 KiCad files?
From the DeMarco/DMH-VCEG repository on GitHub, at the commit this page was made from: the board is DMH_VCEG_PCB_1_Mk1_1/DMH_VCEG_PCB_1_Mk1_1.kicad_pcb and its schematic DMH_VCEG_PANEL/DMH_VCEG_PANEL.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DMH VCEG PCB 1 Mk1 1 design in my own project?
Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
