Questions
How big is the GuitarProcessorBoard PCB?
It measures 86.3 × 67.8 mm and has 4 copper layers, 1.6 mm thick.
What parts does the GuitarProcessorBoard use?
134 parts, built around the TL072, TPS63070RNM, 74HC595 and AMS1117. 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 GuitarProcessorBoard KiCad files?
From the hsetlik/GuitarProcessorH7 repository on GitHub, at the commit this page was made from: the board is GuitarProcessorBoard/GuitarProcessorBoard.kicad_pcb and its schematic GuitarProcessorBoard/Audio.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the GuitarProcessorBoard design in my own project?
Its repository states no licence, so its author keeps all rights: ask hsetlik before reusing the design.
