How To Power Arduino Nano

Arduino Nano is a small, low-cost, board based on the Atmel AVR ATMega328P microcontroller. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It’s intended for use on breadboards and when integrated into projects.

How To Power Arduino Nano

Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328P (Arduino Nano 3.x). It has more or less the same functionality of the Arduino Uno, but in a different package. The Arduino Nano can be powered via the USB connection or with an external power supply. The power source is selected automatically. To power the Arduino Nano with an external power supply, connect the positive lead of the power supply to
