Questions
How big is the Atmega328 PCB?
It measures 35.6 × 48.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Atmega328 use?
26 parts, built around the ATMEGA328-PU. 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 Atmega328 KiCad files?
From the wickerbox/Basic-Breakout-Boards repository on GitHub, at the commit this page was made from: the board is atmega328/atmega328.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Atmega328 design in my own project?
Its repository states no licence, so its author keeps all rights: ask wickerbox before reusing the design.
