user58286: I'm running a pretty basic setup. When I run a small program just doing some serial.println, it works fine, when I try to do operations that needs more power, the brownout detector gets triggered. I'm running my chip on an ok buff power supply so I don't get what the problem is.  




user2881: The ESP typically runs on 3.3 Volt, not 3.0 Volt. 
Secondly, it looks like the board has a voltage regulator, all power goes through the voltage regulator. If that's the case the voltage you need to supply must be lower that the drop-out voltage of the regulator (which is typically around a volt).
