Questions

How big is the FreEDrum PCB?

It measures 250 × 100 mm and has 4 copper layers, 1.62 mm thick.

What parts does the FreEDrum use?

492 parts, built around the SP3485EEN, AD7490BCP, CS4344 and D3V3L2B3LP10. 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 FreEDrum KiCad files?

From the Gemuesesaft/freEDrum repository on GitHub, at the commit this page was made from: the board is Electronics/freEDrum.kicad_pcb and its schematic Electronics/HeadphoneOut.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the FreEDrum design in my own project?

Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
