This is probably a stupid question, but.. I was wondering where the power input on the **(arduino nano 3.0 ATMEGA 328p)** At first i thought it was the ICSP but i was wrong lol, Thanks in advance 😃

It's the pin marked "VIN", just like on the UNO. It's in the corner near the ICSP header.

Okay so it's Vin as positive and Ground as negative? and the max input is like 7V i think.

VIN is positive, GND is negative and 7V is probably the MINIMUM. I think they recommend 7 to 9V.
