What's the supply voltage needed for a Retro Duo, rev3 board? I might be able to figure it out but it's been a long day. Any of you know if the board can take 7.2v straight up or does it need some kind of regulator? Should I not go above 5v? I don't see evidence of one and it's been literally years since I saw a fresh, untampered board.

hmmmmmmm......... i know the earlier versions took 5v straight. like, the power adapter was 5v and there was no 7805 on the board. i've not seen a v3 in person, so am unsure. but i'd imagine they'd not change that aspect, as that was one of their selling points. that it was a "power saver" by only taking 5v.
it's easy to pull 5v off the screen to power the system. it's how i power pretty much all my projects these days. 7.4v to screen, 5v from screen to system.
