I note on the drawings the arduino needs a 6-15v + ground , is it possible to use the +12v and ground from a +12 o -12 supply , (As used in most projects) , if not , I presume a standard 9 or 12v DC supply will be ok

Cheers

> Hmm, I think I read the recommendation is to power a Nano off 7-12V on the VIN pin. I think it’s OK to power it on the 5V pin from an external regulator. But the onboard regulator needs more than 5V in to get 5V out. But don’t take my word for it.
