Questions
How big is the DMH Submodule XFader PCB?
It measures 45 × 45 mm and has 2 copper layers, 1.6 mm thick.
What parts does the DMH Submodule XFader use?
52 parts, built around the TL072 and BC548. 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 Submodule XFader KiCad files?
From the DeMarco/DMH-Submodules repository on GitHub, at the commit this page was made from: the board is DMH_Submodule_XFader/DMH_Submodule_XFader.kicad_pcb and its schematic DMH_Submodule_VCA/DMH_Submodule_VCA.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DMH Submodule XFader 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).
