Questions

How big is the Guitar pedal PCB?

It measures 68.6 × 114.3 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Guitar pedal use?

54 parts, built around the ATMEGA1284-PU, L7805 and NMJ6HCD2. 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 Guitar pedal KiCad files?

From the robtorx/GuitarPedal-ECE411 repository on GitHub, at the commit this page was made from: the board is KiCad project/guitar_pedal.kicad_pcb and its schematic KiCad project/guitar_pedal.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Guitar pedal 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).
