Hello,
So I had a few hours with my first Teensy board and then all of the sudden it seemed to stop working. I had just gotten about half way through the third tutorial (Hello World via serial to the monitor) on the website when I noticed I had no LED activity on the board.
I then remembered that you have to press the button to get the board to boot and load code. I pressed the button several times and nothing.
So I started looking at the board and found that the end of the board where the USB connects was extremely hot.
I unplugged the board and left the board cool down. I re-applied power and checked to see if I had 3.3V at the end of the board opposite the USB connector (per the enclosed pinout card). I did not. And, again, the USB end of the board became too hot to touch.
I also tried to reset the board back to 'factory' code, but there was no indication that the code was written or saved. The board remained inoperable. And hot.
A search of the forums seemed to indicate that this happens from time to time.
Can anyone offer other troubleshooting suggestions?
I really need to get this board back up and running to keep on schedule with my project.
Thank you in advance for your time,
