Questions
How big is the Effect pedal PCB?
It measures 72 × 81 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Effect pedal use?
104 parts, built around the TPS62142RGT, LP5907MFX-3.0, PCM5102APW and USBLC6-2SC6. 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 Effect pedal KiCad files?
From the PenguinOwl/effect-pedal repository on GitHub, at the commit this page was made from: the board is kicad/effect-pedal.kicad_pcb and its schematic kicad-stomp/stomp-board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Effect pedal design in my own project?
Its repository states no licence, so its author keeps all rights: ask PenguinOwl before reusing the design.
