I would if I had enough space. I'm used an uno for my first mock up, and am working on a nano for my full prototype. I plan to program it using the mini usb adapter. I have another question. I'm sure I'm missreading the brd file, but it appears to me that not all of the gnd pins are connected. http://dlnmh9ip6v2uc.cloudfront.net/datasheets/Dev/Arduino/Boards/Arduino-Pro-Mini-v13.zip
What am I missing?
