How to select the Perfect Arduino Board for your project

Many manufacturers make boards with Arduino microprocessors, as it is based on an open-source platform. However, it is highly recommended to get an original Arduino board for your project. To confirm the authenticity, always check that the board bears the Arduino brand name.

However, you don’t need to worry about authenticity for now, as we will be talking only about original Arduino products later in this article. But the real question is, how do you decide which product is perfect for you?

The first deciding factor should be your experience with Arduino boards. Are you a beginner or have you already worked with Arduino boards? You will also have to factor in the requirements of your projects, like how many inputs or outputs the task requires. How many modules need to be connected? Some Arduino boards are even designed for specific purposes, such as boards with GSM modules, boards with GPS modules, and so on.

Next, we will be taking a look at the best Arduino boards that you can buy. We will be comparing the boards based on the microprocessor power, usability, i/o pins, and other important features.

Arduino UNO R3

The most popular, most used, and most documented Arduino board globally is the UNO R3. It is one of the most basic boards and is commonly used by students and beginners. This board is great for loads of DIY projects that are available on the internet. These projects are readily available, complete with codes, equipment requirements, and instructions.

This board has 20 GPIO (General Purpose Input Output) pins, including 6 Analog pins and 14 Digital pins. Serial Communication devices can be connected to this board, too, through Rx and Tx pins. You can also define an additional pair of Rx and Tx pins from the GPIO pins. The connectivity options available on this board will be sufficient for the majority of Arduino projects that you will find online.

These and other features of the Arduino UNO, including a power jack, ICSP header, USB B connectivity, LED indicators, and a reset button make it a perfect solution for students and beginners, all fired by a 16 MHz quartz crystal.

If you need a microprocessor and you are just getting started in this area, the UNO R3 is the perfect board to begin building projects with. It can also be useful for many intermediate-level users who have already worked with Arduino projects, as this board is compatible with a large number of projects.

You can also find several starter kits for your Audrino UNO R3 on the internet. These kits include various devices, modules, sensors, wires, and more, using which you can work on multiple projects. Some of them also come with instructions for various projects that can be done using the items provided. Moreover, you get to be a part of a worldwide community of more than 30 million users.

Arduino Nano

As it is evident by its name, the Nano is a tiny board perfect for small and portable projects. The device might be small, but it packs a lot of punch. It is also compatible with a large number of Arduino UNO projects. However, it has its own set of limitations. With a size of just 18 mm x 45 mm, it is the tiniest in the Audrino board range.

The Nano could be the right choice for students, beginners, as well as experienced users working on portable projects or small IoT (Internet of Things) projects. It consumes very little power, so the only power source is through a USB port. It also has a modest footprint and can be quickly assembled on a breadboard.

The Audrino Nano is based on the ATmega328 chip, which is pretty efficient.

Just like the Audrino Uno, you can program it through the Audrino IDE software by connecting the board to your PC through USB.

This particular board can only be powered through USB and lacks the power jack that is available in the UNO. Due to this restriction, you can only use it to create projects that consume low power. Apart from that, it is quite a useful Audrino board used by many students and intermediate users.

Arduino Mega

The Arduino Mega is for enthusiasts as well as professionals who indulge in larger and complex projects. The full name of this board is the Arduino Mega 2560 Rev3. The key feature of the board is that it has more GPIO pins and Analog pins than the Arduino UNO. Moreover, it has a powerful microprocessor with a RAM and ROM of greater capacity compared to other models. These features, along with others, make it an excellent choice for more significant projects.

If you are going to be involved in such a project, you will know beforehand how many pins you will need on your microprocessor board. The Mega houses 54 General Purpose Input Output pins along with 16 Analog pins. This is a substantial increase in the number of pins from the Audrino UNO. These pins enable you to work on complex projects such as robotics and 3D printing.

The Mega is also compatible with almost all shields (devices, sensors, and so on) that work with the Arduino UNO.

The setup is based on an 8-bit AVR Microcontroller named ATmega2560, hence the name. Rev3 stands for the third revision of the chipset. All the operations on the Mega are powered by an 8 KB SRM and a 256 kb ROM.
