These pins serve as analogue inputs, but can also function as digital inputs or digital outputs. The Arduino® Nano has 8 analogue pins, which utilize ADC (Analogue to Digital converter). You can find 2 reset pin’s and one button on the Arduino® Nano, which are all interconnected. Always make sure that all GND’s (of the Arduino, peripherals and components) are connected to one another and have a common ground. The GND pins are used to close the electrical circuit and provide a common logic reference level throughout your circuit. You can find 2 GND pins on the Arduino® Nano, which are all interconnected. The 5.0V and 3.3V Pin provide regulated 5.0V and 3.3V to power external components according to manufacturer specifications. Take into consideration that this is also used for powering the MCU, its peripherals, the on-board regulators, and the components connected to it. For instance, powering the circuit using the USB limits you to 500mA. The power source you use determines the power you have available for your circuit. The Second one is the USB connector, when connected to the computer, provides 5 volts at 500mA. Above 12 volts, the regulators might overheat, and below 7 volts, might not suffice. The board can be powered by 5-20 volts, but the manufacturer recommends keeping it between 7-12 volts. This pin is used to power the Arduino® Nano board using an external power source. There are 2 ways to power the Arduino® Nano, the first is the VIN Pin.

In this post, we’ll go over the capabilities of the Arduino® Nano pinout. The versatility of the pinout provides many different options such as driving motors, LED’s, reading sensors and more. The Arduino® Nano pinout consists of 14 digital pins, 6 analogue inputs, USB connection and ICSP header.

Arduino® Nano is based on the ATmega328 by Atmel. In this post, we’ll be taking a closer look at the Arduino® Nano hardware, and more specifically, the Arduino® Nano pinout.
