First off you would be better to post this in a post rather than as a reply to this About post. The reason is here this post does not show up as a new post except in the tool bar and thus many people will miss it. Then while it is overall a decent job it has a few issues. Breadboard is typically life size. This appears to be about 1/10 life size (2cm instead of 22cm wide for instance. That isn’t deadly but also isn’t common. As you see it looks a little small connected to a 0.1in header:
although it works fine. As well in schematic you are missing terminalIds on all but the first two pins. That causes the pins to not be on 0.1in boundaries and the pins to connect to the center of the pin for the ones without terminalIds like this:
For starters there is already a ATmega328 in core parts so you are reinventing the wheel. After that your part has a number of problems: In breadboard the chip size is incorrect (it should be 0.3in wide not 0.4)
