Top 25 IoT Development Boards In 2021 And How To Choose The Right One

The world of Internet of Things (IoT) continues to grow and evolve at a rapid pace, comfortably and efficiently complementing the cloud capabilities. Generally speaking, IoT is a network of physical objects that exchange data via the internet.

Every advancement in the IoT market brings more businesses to benefit from the technology, which is getting increasingly sophisticated over time. Research shows that by 2021, there would be more than 10.7 billion IoT devices in use worldwide.

This number is expected to reach $25.44 billion by 2030. Is it not great? From home automation and agriculture to medicine and supply chain, the benefits of IoT cannot be ignored. The technology has the potential to help different businesses with versatile requirements.

The rise of IoT is inevitable 

Not so long ago, human beings produced, processed and analyzed data themselves. They did not have fancy equipment or wearables to do it for them. Legacy hardware came in handy; however, it also had its limitations.

With the advent of the internet and subsequent technologies, a large amount of data can be collected to help any business grow or any human being with a task. Imagine if you have a device that could tell you the best time to water your indoor plants.

Or if a person had fallen down the stairs and needed immediate medical assistance. Or a shipping company wanted to keep track of its fleet and the status of their perishable containers in real-time. All of that can be possible with the Internet of Things.

What are IoT development boards?

As the IoT landscape expands so does the demand for IoT development boards as they can be used for prototyping or in full-scale production. So, what are they exactly?

A development board is simply a printed circuit board with circuitry and hardware designed to assist experiment with a specific microcontroller. Let us break it down.

You have a microcontroller capable of doing many cool things but before it can do all of that, you need to ensure the set up of a group of circuitry and hardware on the breadboard. Engineers mainly use them for prototyping before releasing the main product.

An IoT development board comprises:

Components of a Typical Development Board

  • Programming interface: Lets you program the microcontroller from the desktop
  • Power circuit: Helpful in running off of a 9V power supply
  • Basic output: Buttons
  • Basic input: LEDs
  • I/O pins: Used for temperature sensors, motors, and LCD screens

Key features to look for in an IoT board 

Features For Your Development Board

1. Connectivity superiority

When choosing an IoT board, you must always focus on the connectivity options because — after all — IoT apps cannot function if they are not compatible with or adequately connected to the internet or other devices. So ask yourself the following questions:

  • Does your development board have built-in WiFi?
  • Does it have Bluetooth functionality?
  • Does it support Ethernet?

Speak to multiple vendors and get a demo if possible to understand how the board will work for you and what customization you can do with it, if required.

2. Scalability options

If you are investing money to build a fantastic IoT development board, you must ensure that you can add more functionalities to it. Otherwise, the board will become obsolete faster than ever as the IoT technology advances and businesses need to upgrade their systems. 

3. Peripheral support

Another component to consider is the support for peripherals, including access to common ports like HDMI and USB or pin-outs for PWM devices such as servo motors and dimmable lights. Again, speak to your IoT board development team to narrow down the specifications so that the end product meets your project’s requirements.

4. Processing power

This could be in the form of a microcontroller, CPU, CPLD, or FPGA. The first option definitely comes in handy for programming the IoT-enabled devices as the majority of manufacturers provide the IDE you need for the job.

5. Board memory

Now that is an important feature because to store volumes of data, you need to ensure the board has a built-in Flash memory, which also allows it to connect a MicroSD or a MiniSD and enhance data storage as and when necessary.

6. Wireless capabilities

This feature provides wireless communication excluding an external transceiver module. Some of the common wireless protocols include WiFi, Bluetooth, and Zigbee.

Also verify if the board communicates through SPI, UART and GPIO to understand how the board will interact with other devices.

Three types of IoT board categories

Categories of IoT Boards

1. Microcontroller-based boards

Even if you are new to programming and electronics, you must have come across the term “microcontroller boards.” They comprise a small computer developed on a metal oxide semiconductor circuit chip, and are mainly used in implantable medical devices, office machines, power tools, automobile engine control systems and so on.

Programming enthusiasts use the same microcontroller-based boards for learning purposes and Do-It-Yourself (DIY) projects.

2. System-on-Chip (SoC) boards

A SoC board incorporates many system components into a single Si chip, primarily consisting of an audio receiver, memory, peripherals like USB, PCI and SATA, a microprocessor, and an application processor — basically all the required electronic components and circuits.

They find use in a number of industry niches, including medical care where SoC-based nano robots can perform as programmable antibodies to fight serious illnesses. SoC-based video and audio devices can be installed in the brains of blind and deaf people respectively.

Another benefit is that it can deliver high clock speeds while decreasing the power spent by a microchip, if used along with SoI or Silicon-on-Insulator.

Of course, SoC is an evolving technology and some of these examples might seem impossible at the time. However, it does hold a lot of promise in the years to come.

3. Single-board computers (SBC)

This is an easy one. As the name suggests, it is an entire computer developed on one circuit board. It comprises all the features of a functional computer such as memory, microprocessor(s), input/output (I/O) and so on.

SBCs are usually built as development or demonstration systems. A huge variety of portable computers and home computers integrate all their functions onto one circuit board easily. SBC designs are simple and they do not often rely on expansion slots for peripheral expansion.

Many other types of blade servers perform almost like server computers, although in a more compact format.

Selecting the right IoT development board for your project

There is no doubt that there has been a massive increase in the development of low-cost, low-power IoT development boards in the electronic industry. From Intel to open-source Arduino, all brands have stepped up their game to beat competition in the fast-paced IoT sector.

Regardless of what you decide to develop, it is important to choose the best IoT development board. Since it serves as the brains of your project, you cannot take this step lightly.

You must choose something that can communicate with all interconnected electronic components with rather ease. So here are the three key steps you must take to ensure you make the right decision. Good luck!

Right Development Board For Your Project

1. Confirm the development board type

Your development board could fall under several categories as per design and specification. As discussed previously, it could either be a microcontroller board such as Mega and Arduino Uno or a SBC like the BeagleBone Black and Raspberry Pi.

Confirm your project type. Is it visual-focused or sensing-based? Whatever it is should dictate your choice. There is a possibility you might have to use more than one type of boards. For instance, pairing a Raspberry Pi with Arduino Uno would fetch you better results.

Therefore, research thoroughly before making any decision because it is going to stick with you throughout your project, and you do not want it to hamper your progress.

2. Observe the programming language and community

What programming language you use is an important factor to consider in the IoT development board. For example, you could need support for multiple languages, OS and IDEs to create a rich and wholesome experience.

C and C++ are universal programming languages and many boards support them or a similar language like them. On the other hand, IDEs for some boards will allow you to experiment with more than one programming language.

Then there are single boards that usually run on Linux. For instance, the most popular OS for the Raspberry Pi is Raspbian. You also need to ensure you have a strong community of the programming language to fall back on.

Otherwise, it will get pretty difficult to get help in case you hit a roadblock in your project and your programming language offers limited support. So, choose wisely!

3. Check the specifications of the board

The thing that the specifications of your development board have been to be larger is wrong. As long as they get the job done it is important.

Also, the board with more specifications usually costs more and second, it sometimes creates more problems if the development team is not that experienced in working with complicated boards before.

Therefore, it is best to find a medium spec board. Of course, if you plan on adding more functionalities to the board down the line, then opt for better specs.
