Cool... I want oneHey but can you break out the rest of the pins?? You could make a 2-wide header that goes along an edge, kind of like Maple.
What is the big pad around U1 for? A heat sink?
Yes, played with a heat sink. My first time relying on board copper for heat sink. Used TO-220 and heavy duty metal in the past. So this board is a bit of an experiment to try a few things, and to keep a couple of projects moving that need more RAM then the 328 has to offer.
Will be playing with the board some more based on the outcome of the prototype and any suggestions and ideas I receive here.
I committed this one to being made. I'll be getting 10 boards in the mail. I only need 2. If the first build doesn't go up in smoke there'll be a few bare boards I am gladly willing to pass along.
