Questions

How big is the KICAD PROJECT PCB?

It measures 89.5 × 121.6 mm and has 4 copper layers, 1.6 mm thick.

What parts does the KICAD PROJECT use?

150 parts, built around the PAM8302AADCR, TPS61032PWP, PCM5102APW and RP2040-ZERO. 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 KICAD PROJECT KiCad files?

From the IstratieStefan/ARC-Hardware repository on GitHub, at the commit this page was made from: the board is KICAD PROJECT/KICAD PROJECT.kicad_pcb and its schematic KICAD PROJECT/KICAD PROJECT.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the KICAD PROJECT 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).
