Questions
How big is the Prototype board PCB?
It measures 221 × 101.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Prototype board use?
70 parts, built around the TL072. 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 Prototype board KiCad files?
From the theWickedWebDev/Modular-Synth repository on GitHub, at the commit this page was made from: the board is 00_PROTOTYPING/Solderable-Breadboard/prototype-board.kicad_pcb and its schematic 00_BREAKOUTS/Breakout-AudioJack/AudioJack-Breakout.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Prototype board design in my own project?
Its repository states no licence, so its author keeps all rights: ask theWickedWebDev before reusing the design.
