The manual says it is pin 30 that takes in the external power. I would like to be able to run my arduino also stand-alone with this 9 V battery.
I can't find any label 30 on my arduino nano v. 3.0.
If 9 volts is not possible, thanks for letting me know. So it the right pin the VIN pin to connect my red cable and the black goes to GND?
Thanks for info again...,
