Questions
How big is the GuitarZero PCB?
It measures 160.5 × 102.9 mm and has 6 copper layers, 1.6 mm thick.
What parts does the GuitarZero use?
146 parts, built around the TPS54325PWP and PCM1754DBQ. 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 GuitarZero KiCad files?
From the jonatso/GuitarZero repository on GitHub, at the commit this page was made from: the board is pcb/GuitarZero.kicad_pcb and its schematic pcb/DAC.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the GuitarZero design in my own project?
Its repository states no licence, so its author keeps all rights: ask jonatso before reusing the design.
