To Power your board from an external 5v power supply, you have to wire the 5V of your source to one of the 5V pin of your Board (two pins available on the connector P2) and the GND of your board to on of the GND pins of the Board.

I done the same way you mentioned above with LDO that reduces the battery voltage to 5V and connected to the board through one of the 5V pin but, the board was gone.

Is there any other things we have to follow for the external power supply please mention that.
