The power consumed by Arduino Nano, according to the official Arduino website, is 19 mA. The regular USB port wouldn’t have looked as good on the nano board as it does on the Arduino Uno. The designers must have used a smaller USB port for the Nano board because of its small size and delicate PCB. Arduino Nano has a micro-USB port that connects it to the computer, while the Uno board uses an A/B USB connector. The second significant difference between the two boards is in the USB port. The UNO board, however, has the option of powering it via a DC adaptor. The first one is the absence of a DC barrel connector in the Nano board, which is a handy feature when it comes to powering Arduino without a battery. Now let’s look at some of the significant differences between the two boards.
Both boards have the same power pins 5V, 3.3V, GND, and Vin. Arduino Nano has 8 analog pins while the Uno board has 6 of them. PinoutĪrduino Nano and Uno both have 14 digital I/O pins, while the Analog I/O pins are not equal. Let’s see how it compares with the Arduino Nano. The Uno board has everything that you would want in a basic microcontroller board. To see how well Arduino Nano works, let’s compare it with the viral Arduino Uno board, which many people believe is their go-to microcontroller board. Hence, you can rely on Arduino Nano for all your electronic project needs whether you are a student or an electronic hobbyist, this board offers everything that you need. It is controlled by the powerful ATMEGA328 chip, which offers a clock speed of 16 MHz, just as much as other Arduino boards. You can use Arduino Nano in a wide variety of projects ranging from simple LED blinking projects to complex IoT applications. Arduino Nano has all the functionalities of other Arduino boards with an added advantage of compact size. However, it does not have a regular USB dock instead, it has a micro USB port to connect it with a computer/laptop. Similar to other Arduino boards, it has digital and analog I/O pins along with power, GND, and reset pins. It is convenient in situations where you are looking for a board that can fit into tiny spaces without any hassle since it is breadboard friendly. It is one of the most widely used Arduino boards all around the world, mainly because of its unique physical dimensions. It is a powerful yet very compact microcontroller board, almost half the length of an Uno board. To compare the two boards, you must first know what the Arduino Nano is. Looking for the best Arduino for beginners? I wrote a complete guide comparing costs and features of the best boards for beginners here: /best-arduino-for-beginners/ What Is The Arduino Nano? Below, I’ll cover these aspects and discuss the features of each board separately so that by the end of this article, it’ll be easier for you to decide which board to use in your upcoming project. Similarly, there are many other aspects on which the two boards are comparable. The compact Arduino Nano is ideal for projects where size is an issue, while Arduino Uno does not have such restrictions.
Some projects demand the use of Arduino Nano while others especially require the Arduino Uno board. It mainly depends on your project’s application. Nano: Which Board Is Better? Each board offers a different set of pros and cons, which makes it challenging to pick one board out of the two. So, I thought I’d write an article to share my learnings in the form of a comparison between the two amazing Arduino boards: UNO and Nano.Īrduino Uno vs. I explored other Arduino options and found the Nano to be one of the best ones out there.
