Questions
How big is the Matrix Mixer v1.0 PCB?
It measures 102.5 × 128.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Matrix Mixer v1.0 use?
94 parts, built around the 1N5819WS. 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 Matrix Mixer v1.0 KiCad files?
From the StudioKAT/MatrixMixer repository on GitHub, at the commit this page was made from: the board is v1.0/KiCAD/Matrix Mixer_v1.0/Matrix Mixer_v1.0.kicad_pcb and its schematic v1.0/KiCAD/Matrix Mixer_v1.0/Matrix Mixer_v1.0.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Matrix Mixer v1.0 design in my own project?
Its repository states no licence, so its author keeps all rights: ask StudioKAT before reusing the design.
