I tried applying 12V through the CDC connector (until now I had only applied 3V3 through the 6 pin header) and on the v3.2 board that I have, there is a point market 3V3 right near that connector. The voltage there was only a fraction of a volt and the voltage regulator was hot enough to fry eggs, so I'll be looking for a short somewhere before doing anything else.  :-)

@homerisback, I also did that deliberate short between GPIO7 and GND on the RN52. I see an ArduinoISP sketch in the Examples of the IDE, I assume that's the one you used.  However, according to the comments in that sketch, it looks like on an Uno I should use the SCK, MISO and MOSI pins which are on the ICSP header or are pins 11,12,13.  I'm wondering how it worked with pins 5 and 6 on your Uno.  It's a bit of a pain prying the 328 in and out of the Uno, so I'd like to try this method once the power issues are sorted out.

Thanks!
