June 24, 2021

IoT is an extensive domain rising at a rapid pace and engaging the industry’s big players. With modern age transformation, the number of available IoT development boards is also mounting. But, there is not any single IoT board that we can consider the best for multiple reasons.

The IoT apps have different requirements and need to use plenty of IoT boards to address those requirements. There are several IoT ecosystems based on various connectivity solutions. It can be easily applied to one board but not to another. The IoT apps can be hardware-oriented in one way while software-oriented in other ways or might need a balanced percentage of computing power and hardware choices inside the same app.

There are also different IoT platforms and some of the IoT boards specifically designed to connect with proprietary platforms.

What is a Development Board? Why is it used?

A development board is a circuit board with wiring and hardware designs that will help to experiment with specific microcontrollers. These boards are created to make an engineer’s life easy and efficient while prototyping and developing.

Just imagine, you have a microcontroller that can perform many things but to leverage it, you need to set up initially a group of different circuits and hardware on your breadboard every time. It’s quite an irritating task for smart engineers nowadays, to set up circuits every time. To overcome this issue, hardware circuits are helpful with testing and debugging.

Aspects to consider while selecting an IoT board

You can choose wisely by filtering your needs based on the following aspects.

  • Project size
  • Necessary connectivity solutions
  • App purpose
  • Essential IoT protocol(s) implementation
  • Firmware complications at every node
  • Necessary connection with particular IoT platform
  • Support of community
  • Compatibility of Hardware and Software among several nodes in the IoT network
  • Size of the IoT device or the object
  • Software support (libraries to apply IoT protocols, sensor integrations, data obtaining)
  • Number and type of sensors to be incorporated at multiple nodes
