Did I damage my board?
Posted: Tue Apr 12, 2016 3:15 pmIt started to throw some exceptions at me yesterday. So I flashed the firmware today as described here: http://www.allaboutcircuits.com/project ... fi-module/
That worked well (except the Putty part, that won't output the AT command at all).
Than I flashed this small sketch with the Arduino IDE:
Running this sketch, I constantly seeing exceptions like this in the serial console:
Did I damage the boar somehow? Is there something else wrong? Should I provide more power? (running it from USB currently with a LD1117V33 between)
thanks and greetings,
André
