An Arduino board is a crucial instrument for discovering new things. Anyone – teenagers, hobbyists, musicians, programmers – may start tinkering by following a kit’s step-by-step directions or by exchanging ideas with other members of the Arduino kit community.
Pros of Arduino boards:
- Simple working with microcontrollers;
- Versatile and made for beginners among students, teachers and DIYers;
- Cross-platform and open-source software. It supports the operating systems: Windows, Mac OS, Linux, etc.;
- Clear development environment thanks to the Arduino Software (IDE);
- Advanced hardware. In order to learn how it functions and save money, even comparatively novice users may create the module’s breadboard edition;
Make sure to check the buying guide and comparison table below to find the best arduino board according to your preferences for size and features.
ARDUINO UNO R3 – the best for beginners!
The Arduino UNO R3 board is open-source hardware, but using the files accessible on the Arduino website, you can create your board.
With IDE tools, the UNO board can be configured. You can pick from any Arduino on the system menu, based on the microcontroller on your board.
Through utilizing the initial STK500 protocol, the ATmega328 microcontroller on the Arduino Uno board communicates.
A CD with a detailed guide is provided, and the code for how to use the different modules. Modules are pre-soldered and require clear wiring.
There is a premium-feeling acrylic case complete with rational and carefully stored bits and components in separate compartments. The approach to holding your Arduino projects coordinated is a solid one.

- Dated use guide;
This board is your gateway to the special Arduino experience: perfect for understanding the fundamentals and an important platform for your quick prototyping needs.
Arduino Mega 2560 REV3 – the Most Powerful Arduino!
The Arduino Mega 2560 is built for the most creative projects that need extra pins and extra memory and power.
It could be a perfect option for smaller DIY ventures that need room to grow, the Arduino Mega 2560 R3.
It contains all the microcontrollers required to support; only attach it to a device with a USB cable or power it to get started with an AC-to-DC adapter or battery. Most shields developed for the Arduino Uno, Duemilanove or Diecimila are compatible with this Mega board.
For all current shields, the Mega 2560 R3 fits but will adjust to new shields that use these additional pins.
- Many pins for IoT modules;
- 4 UART terminals;
- Compatible with most shields;
- A lot of memory;
- Lacks some turnkey features;
In terms of the amount of pins or header contacts, board size and memory size, a 2560 board is simply a larger Arduino Uno. Except for the price, all the benefits of the Arduino Uno refer to the Mega 2560.
Arduino Due– the best for flash memory size!
Arduino Due is a microcontroller board focused primarily on the Atmel SAM3X8E (32-Bit ARM microcontroller). Compared to Nano or Uno, it is a large module and it comes with more pins and memory space compared to them.
Using a standard Arduino Software (IDE), which is compliant with all Arduino boards, the Arduino Due can be configured and can function both ways: online and offline.
- Fast processor;
- Cheaper than the Mega board;
- Improved flash memory;
- Limited 3.3V pins;
- No IoT features;
Arduino Due is bulky, but it covers vast spaces and is used in a wide variety of applications where the necessary outcome is high processing speed.
Arduino Leonardo with Headers– the best for USB compatibility!
For a link to your PC, the Arduino Leonardo header board uses a Micro-B USB cable, which is a move apart from the USB Type-B connectivity featured in Uno.
What makes it distinctive from other Arduino boards is the inbuilt USB 2.0 connectivity. Through this, the Leonardo will connect directly through USB with your PC, enabling it to function as a mouse or a keyboard. It opens up the potential for even more fascinating applications with the assistance of the Keyboard Library.
If you require a few more IO pins, USB keyboard or mouse identification, as well as all the characteristics of a Uno board, then the Leonardo could be just what your project wants.
- Has many analog and digital pins;
- Has a microUSB instead of a USB-C port;
- Cheap but powerful ATMega microcontroller;
- Includes headers;
- Not compatible with some shields;
- Limited features;
- Lacks IoT functions;
A good place to begin is the Arduino Leonardo Board. Starting up on the board is not a challenging challenge since by Arduino IDE, it is relatively close to other Arduino boards.
Arduino Nano– the best for breadboards!
Slightly smaller than the Mini, the Arduino Nano is similarly built to work on a solderless breadboard. The Nano, though, operates on the same processor used in the Uno, the ATmega328 MCU.
With the same barrel jack-less configuration as the Nano, it uses a Mini-B USB socket.
Surprisingly, there is more RAM on the Nano than on the Mini. This is attributable to the bootloader on the ATmega328 being smaller. The identical boards with distinct cores are the Micro and the Nano modules.
The Nano is a lightweight board ideal for nearly all DIY electronic designs, but there is a broad variety of Arduino boards to choose from. These tiny microcontrollers allow the production of portable DIY hardware accessible to more individuals than ever before.
- Good for novices;
- Tiny for small projects;
- Simple prototyping;
- Includes a mini-USB cable;
- Limited IoT uses;
- Limited memory;
The Arduino Nano is the Arduino Uno’s “little brother” that shares much of its features. Other than its smaller scale, the biggest distinction being the USB connector, with the Nano connected via a micro USB cable to your device.
To study hobby electronics and programming on it is a perfect microcontroller, and its size makes it ideal for building into projects that need a limited form factor.
