Hello everyone!
I have a silly question that unfortunately I cannot figure out by myself! I want to create my first solid project and I want to install an Arduino nano on a case. Thus, I don’t want to power my Arduino through USB port, as I need the usb port to be easily accessible. At this point I am considering on powering the board via Vin input. However, I am not entirely sure how much voltage I can apply! Is there a regulator between the Vin pin and the rest circuit or I simple can apply 5V directly?
