Hey I'm doing a prop project, I have arduino nano board and adafruit 24LED ring. But I need to connect arduino to a portable battery. So I have battery pack wich output voltage 10.8 - 12.6V DC and output current is 1-2A.
Just to be clear I need to connect positive side to Vin and ground to any ground pin? And is it safe to connect 12,6V to arduino nano or arduino uno?
