Yes, as long as you use the correct 5V pin you will be fine.

It does not get hot and at least on the board I got, all the components were rated to at least 40V so the 30V limit is lower than what the actual hardware can handle. The 5V input goes to an ams1117 which is rated to 15V, but that will get very hot if you power it with more than about 9V.
