Arduino Nano Pin Configuration

Pin CategoryPin NameDetails
PowerVin, 3.3V, 5V, GNDVin: Input voltage to Arduino when using an external power source (6-12V).

5V: Regulated power supply used to power microcontroller and other components on the board.

3.3V: 3.3V supply generated by on-board voltage regulator. Maximum current draw is 50mA.

GND: Ground pins.

ResetResetResets the microcontroller
