I guess the subject says it all. According to the datasheet, the mega328 can run off of voltages from 1.8 - 5.5V. I know that Vin goes to the voltage regulator but the 5V pin I believe goes straight to the mega328 so can I just put 3.3v on that pin and run the whole nano at 3.3v?

Is it possible to run a nano at 3.3V?
