Questions
How big is the Diym2 PCB?
It measures 75 × 45.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Diym2 use?
52 parts, built around the LM358, AMS1117-3.3 and IRLML0040TRPBF. 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 Diym2 KiCad files?
From the open-domophone/hardware repository on GitHub, at the commit this page was made from: the board is kicad-project/diym2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Diym2 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).
