Frequently asked questions
How can the Nano be powered?
It can be powered over USB. For external power, the Nano's VIN pin accepts a regulated supply, typically 7 to 12 V according to the Arduino Nano datasheet.
Does it fit on a breadboard?
Yes. The pins use the standard 0.1-inch spacing, so the Nano fits standard breadboards directly.
