Questions
How big is the Multiple PCB?
It measures 38 × 98 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Multiple use?
25 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 Multiple KiCad files?
From the mtihlenfield/diy-synth repository on GitHub, at the commit this page was made from: the board is multiple/multiple/multiple.kicad_pcb and its schematic keyboard/hardware/keyboard-controller/analog_input.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Multiple design in my own project?
Its repository states no licence, so its author keeps all rights: ask mtihlenfield before reusing the design.
