Questions
How big is the Project1 PCB?
It measures 35 × 20 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Project1 use?
39 parts, built around the STM32G431KBU6, MIC5501-3.0YM5-TR, IM69D120V01 and SP0502BAHTG. 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 Project1 KiCad files?
From the embeddedalpha/PCB-Design repository on GitHub, at the commit this page was made from: the board is Sound Capture Board/Project1.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Project1 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).
