Types of Arduino Boards with Specifications

Last Updated on December 5, 2024 by Swagatam 22 Comments

In this post we present a list of around 20 popular Arduino boards that are used by engineering students and professionals for their specific application needs. The types of Arduino boards discussed here are designed with a range of unique features and specifications to suit a desired application in the most effective way. The range of Arduino boards allow the students and hobbyists to select the right unit depending on their budget and the complexity of the task they want to implement.

What is an Arduino Board?

Arduino is an open-source electronics platform developed using easy-to-use hardware and software. Arduino boards have the ability to read inputs such as light falling on a sensor, a touch of a button, or a Twitter message, and transform it into an output which can be used for switching an external parameter ON or OFF.

This external parameter can be like turning a motor or an LED ON/OF, or even submitting a content on the internet.

Arduino enables the user to command the board a range of tasks by delivering a handful of information to the microcontroller on the board. To do this the user implements the Arduino programming language (depending on Wiring), and the Arduino Software (IDE), determined by Processing.

Arduino Boards and their Applications

The following content provide a list of popular Arduino boards along with detailed specifications, which can be selected by the user depending on the complexity of the application.

For example, if you are an engineering student and just getting started, you would need a board that are cheaper and less complex to use. These may include: Arduino-UNO, Arduino-Leonardo, Arduino-101, Arduino-Esplora, Arduino-Micro, Arduino-Nano etc.

For advanced users who now want to execute complex codes and programs, they can select from a range of these advanced and fast Arduinos such as: Arduino-Mega, Arduino-Zero, Arduino-Due, Arduino-Pro, etc.

    Thank you Swagatam for the many circuits.
    I want a circuit designed for the measurement of tensile strength of thin films such as polythene, etc. The film is to be clamped between two jaws which will travel in opposite directions (a jaw may be fixed while the other travels). The force required to pull the film till it breaks and the distance travelled are measured and displayed.
    Thanks.

    Sir,
    Good afternoon,
    I am planning to do a project on water seepage detection. Can you please suggest a suitable board and sensors.
    Thanking you for your time,

      Hi Vishwa,
      If you know the coding and programming procedures, then you can simply use the UNO board for the project. For seepage detection any moisture sensor device would work.

    Hi,
    I’m looking to use an Arduino MKR WIFI 1010 to control a DC-DC PWM Buck converter, similar to one of your projects (www.www.homemade-circuits.com/buck-converter-using-arduino/). I would like to have the converter operate at 100kHz. Is this achievable? Would one of the other boards be better? The maximum frequency of your project was 62.5KHz, I would like to get my frequency up to 100 kHz. My ultimate aim is to implement a digital closed loop controller.

    I would greatly appreciate any help you can give. Thank you.

      February 11, 2020 at 1:14 pm

      Hi, According to me it is definitely achievable since MKR WIFI 1010 board is an enhanced version of the MKR1000 and is perfectly suitable for 100 kHz PWM operation.
