Questions
How big is the FrontBoard PCB?
It measures 60.5 × 112.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the FrontBoard use?
54 parts, built around the TL074CN. 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 FrontBoard KiCad files?
From the richardjmarini/MatrixMixer repository on GitHub, at the commit this page was made from: the board is FrontBoard/FrontBoard.kicad_pcb and its schematic FrontBoard/FrontBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the FrontBoard design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
