I want to know if it is possible to supply power to raspberry pi 3 with AA batteries.

Some electronic boards like Arduinos contains a voltage regulator. The Vin voltage input can be greater than 5V.

But i don't know if raspberries devices contains a regulator. Do they need exactly 5V ?

    At some point in this folly, you may wonder how long my RPi will run from AA batteries. When you reach that point, there are some calculations that may help.

Yes, can be done with a voltage converter.

I use 6x AA NiMH Eneloop Pro batteries which give about 7.2 volts along with a voltage/buck converter to step the voltage down to 5 volts.

    And how many minutes does it run?

  • This isn't "useful" IMO.

The maximum input voltage is 5.25v and a standard aa battery is only rated to supply 50ma of current so running a pi from aa batteries is not really feasible

    the term is AA, not aa

There are many things wrong with this approach.

AA batteries are not capable of supplying sufficient current; NiMh cells would be marginal.

The Pi has no regulator and operates over a narrow voltage range.
