FAQ:

Q: Does the ardiuno nano have a serial2 port?

A: All Arduino boards have at least one serial port (also known as a UART or USART), and some have several. On Uno, Nano, Mini, and Mega, pins 0 and 1 are used for communication with the computer. Connecting anything to these pins can interfere with that communication, including causing failed uploads to the board.

Q: Is Uno and nano compatible?

A: The UNO and Nano use the same processor which means that in terms of hardware and peripherals the UNO and Nano are identical . If a project requires plenty of GPIO, the Due and Mega are the obvious choices.

Q: What is the use of Arduino Nano?

A: The smaller version of the Arduino Uno, the Arduino Nano, is often used for projects where space for the board itself is very limited. Like its larger counterpart, it is based on the powerful ATmega328 microcontroller from the US company Atmel , and it can be used for simple and complex projects alike.

Q: What are the dimensions of an Arduino Nano?

A: The Arduino Nano, as the name suggests is a compact, complete and bread-board friendly microcontroller board. The Nano board weighs around 7 grams with dimensions of 4.5 cms to 1.8 cms (L to B).
