Thanks so much for all your help William! I went into purchasing the BB Blue with eyes wide open, knowing it's brand new. When the board was working I was very impressed with the cloud9 IDE and the capability to even use a terminal directly from a web browser. I only worked with the onboard IMU and barometer and didn't connect any other external devices yet.
I contacted the vendor I bought this from (Newark/Element 14) and they provided me a full refund within 2 days! Great customer support! I'll wait awhile to see if others have success with their batch of the board and give the Beaglebone Blue a try again in the future. (I also entertained buying one of the more well used versions, but I really like the integrated IMU so I'll wait) Thanks for all the help guys!
