Pro mini is actually a cut-down version of Nano. It is also a very popular choice among the developers just like UNO because of its small size and cheap price. Nano uses an FT232, a dedicated USB-UART bridge chip from FTDI instead of an ATMega16U2. The only major differences from UNO are the lack of a DC power jack, the usage of a Mini USB port instead of a USB B port, and the USB-TTL converter chip. It has more or less functionality of the Arduino UNO but in a small form factor. Arduino NanoĪrduino Nano is a small breadboard-friendly version of Arduino UNO. Hence the color or the appearance of the board might be different than what is shown above.

Now, there are many different types of Arduino UNO boards available across the global market, but most of these boards are the clone or copy version of the original UNO board that you see above. It consists of 14Digital I/O out of which 6 pins are 8bit PWM pins, 6 pins are10-bit Analog inputs, and basic communication ports like SPI, I2C, and UART. It is the most popular choice among the community because it’s, cheap, easy to learn and use, and also a variety of premade modules are available for this which makes it easier for developing new projects or prototypes. It is powered by an ATMega328P microcontroller. *click on the above image for full view Arduino UNO R3Īrduino Uno is the most popular and widely used development board. Here is the table showing all the features of these boards. Not only that, there are a variety of modules and shield boards available on the market, especially targeting these base-level boards. Most of them are easy to learn and make projects with.

All these boards are powered by 8-bit microcontrollers. In this category, most boards have either slow clock speed or a limited number of I/O ports. These types of arduino boards are the best choice to start with. Further, we have also provided a table under each section for quick skimming, so let’s get started. To make things quick and easy for you, we have split all the boards into three main categories, Entry Level boards, Enhanced boards, and IoT boards. So this tutorial is focused on bringing out all the different types of Arduino development boards and doing a quick comparison of their features and applications so that you will be able to make a better choice when you want something more than the popular UNO and nano boards.

But most of us fail to explore beyond the popular Arduino development boards like the Arduino UNO, nano, mega, etc.

For hobbyists and engineers, including me, Arduino Platform has been the go-to place for quick prototyping and design validation. Whether you're a newbie just getting started with electronics a nd e m be d d ed sy stems or a p ro fes si o nal E nginee r pla nning your n ext big desi gn p roj ec t , Arduino has you all covered with a Development board that best suits your requirements.
