Questions
How big is the Atmega PCB?
It measures 18.8 × 23.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Atmega use?
11 parts, built around the ATMEGA328P-AU. 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 Atmega KiCad files?
From the theapi/touch_timer repository on GitHub, at the commit this page was made from: the board is kicad/experiments/atmega/atmega.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Atmega 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).
