you can get 5v from the link port (it's sometimes tricky to get a link cable connected to it properly, but you can always mod one...)

I have an arduinoboy that is powered this way, so you could use this to power the nano.
I think you can just use a step up converter to get from the lipo to 5v (but maybe do some googling as to one that is suitable to use with the lipo?).


Even though I knew most of what was in that article it was a good read, thanks for the input!  I realized now that I forgot I am using 2 arduinos since one is my arduinoboy and the other is my own for the midi (I'm not proficient enough in programming  enough to combine the two lol).  That being said, I looked into some options and one easy method that may work for me is I found a powered USB hub I could plug into a batter or power bank and distribute power to each with a simple usb.  Figured i would share to see if anyone had thoughts on that method, also is it more efficient to downvolt or up? Because I could get a 9v and downvolt  it.  Logic feels like lowering the energy would be easier than boosting.

This is probably useful - and says the Pocket steps up the 3v from the batteries to 5v internally which I think probably suggests the gameboy architecture is based on 5v too...

Ultimately I wanted to confirm some of these values I was reading and see what people suggest, thank you in advance!
