Wow, i have never had so many issues with an Arduino board as i have with this one. Uploading fails 99% of the time. 'avrdude: stk500v2_ReceiveMessage(): timeout'. Common problem if you google it. Have tried every suggestion out there. Next step is apparently to upload a new bootloader,. I am going to keep battling with it, but unless you really need the extra pins stick with a board that works, see if the extra pins on the Leonardo or Nano will get you going. This mega clearly has issues.
