Re: Arduino Hangs
Yes. I cut the 3.3V pin from the Nano to the PCB and the voltage went down to 3.5, which is a little high but OK. The 3.3V from the Nano is not used anywhere on the Nano, it comes out of the USB chip and goes to the connector, nothing else. I suspect that at $3 each, not much testing is done on those Nano boards, although you would think that a high volume product would use a simple bed of nails tester to check all the I/O etc.
I liked the Adafruit board because it has 5v to 3.3V level translators and its own 3.3V supply. It was mailed to me today, so I should have it tomorrow or Saturday since Adafruit is about 20 miles from my QTH. Plus it is a pain to solder those tiny chips.
Thanks for all the help.
