Questions
How big is the Pedalshield PCB?
It measures 53.3 × 101.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pedalshield use?
73 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 Pedalshield KiCad files?
From the inktrap/pedalshield repository on GitHub, at the commit this page was made from: the board is kicad/rev-E/pedal shield.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pedalshield design in my own project?
Its repository states no licence, so its author keeps all rights: ask inktrap before reusing the design.
