Questions

How big is the Chops PCB?

It measures 100.2 × 30 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Chops use?

8 parts. 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 Chops KiCad files?

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

Can I use the Chops 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).
