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.
