I think the idea is that it works basically like a normal Uno, with the addition of Wifi and stuff. So you can power it from a 5v supply, but not from only a 3.3v supply (without boost circuitry).</p>

One question about power: if I have external 5v and 3.3v power supplies, can I power the board with them, instead of the onboard voltage regulator and the USB input?<p>Thanks.</p></p>
