Did you mean to connect AVCC to ground?

Edit: oops, misread it, it's the pad next to AVCC that's connected to ground. That makes a bit more sense...

Sparkfun pro mini and a 28 pin dip socket.

For reduced size on a breadboard smt isn't going to help that much. The smt mega168 is about the same width as a dip socket and you need extra space to break out the pins.

Don't forget this one, from the guy who sorted out the serjtag package:


Who needs a board? :)

Version 2!

This one adds a voltage regulator, a reset button, and a few other minor changes. It has everything the Arduino pro mini has except the power indicator led (not enough room to hand-route the 5V line). I also moved everything to the top of the board, except for the led, which makes soldering easier. The board is 2 inches long, .9 square inches.







Better photos too!

Still using the internal oscillator, though?
