Questions
How big is the PedalIntermediate PCB?
It measures 22 × 30.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PedalIntermediate use?
19 parts, built around the AP63203WU and AD5241BRZ1M. 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 PedalIntermediate KiCad files?
From the rolfluc/VCR repository on GitHub, at the commit this page was made from: the board is PedalIntermediate.kicad_pcb and its schematic PedalIntermediate.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PedalIntermediate design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
