Hi,
I love my
UNO's, and all its clones, but specially the DIP package, its nice and BIG and I can see it, and I can solder and plug it into 0.1inch vero when making stand alone projects.
The variety of UNO clone boards, with extra pins for servo to be plugged and extra parallel SDA and SCA pins on some clones makes life so much easier at times.
As you may gather, I find no reason why everything has to fit on a PCB the size of a postage stamp.
Tom...
The clones were bought on ebay, at auction, for less than $5 limit I put on the bidding.
I have 6 UNO, 2 DUE, 2 MEGA and 5 ATtiny85 USB Chip(have not played with them yet).
