Unless you are using the features of the USB chip what about the nano on its terminal board like I showed? The combo is smaller than the UNO and has more inputs.
I already have the uno and don't want to buy another arduino. I actually almost bought that one in the first place because of its size but liked that the uno has boxes already made for it. Problem now that I didn't see when I started was how to get the screw terminals to fit in the box as well.
