External 5v gameduino 2 power pins

[BrewBot]

In an effort to reduce the current flowing through my Arduino board, would it cause any issue to externally power the gameduino 2 vin and ground pins?

If this is possible, are the Vin and ground pins as highlighted the correct ones for powering externally?

Yes, those two are the power inputs - external 5V power works fine.
