Fully functional board!
I've thoroughly tested the board today. No not just the blink sketch. Checked all serial communications, which all work, including the icsp headers. Ran a sketch that loops through pins for testing. Board has performed flawlessly for testing. I've yet to use it in the project I bought it for but I'm happy to start building around it. The testing included the cable that came with it. The only thing I haven't tested directly was the power jack. I'm using my power cable to charge some batteries at the moment, so this will have to wait for tomorrow.
