Are you a circuit designer looking for some tips to incorporate IoT in your PCB designs? Does the thought of implementing IoT seem challenging to you? If yes, then you are in the right place!

IoT has significantly gained popularity in recent years due to the increase in digitalization in all walks of life. All major electronics manufacturers are moving towards implementing IoT based designs, and some companies such as Google and Apple have captured the IoT market quickly.

What does it take to incorporate IoT into your product? What advantages does IoT offer when used in PCB related projects? Read on to find answers to all such IoT related questions.

What Is IoT?

Internet of Things (IoT) is the interconnection of electrical, mechanical, and electronic devices over a network where these devices can communicate with each other without the need for human supervision or interaction. Soon we will see that everything inside and outside our homes is online, be it devices, animals, plants, or even human beings.

What makes IoT so compelling that it gained so much popularity in such a small amount of time? The most significant advantage that IoT offers is that humans don’t have to bother monitoring basic things in the house. They can save a lot of time because the devices will track everything on their own.

What Are the Requirements for IoT Based PCB Designs?

As a designer, to introduce IoT in your PCB designs, keep a few things in mind. Introducing IoT means that your PCB design must suit your targeted audience; hence, there are specific requirements that designers need to keep in mind when working on IoT related projects.  Check out these top seven areas to consider:

1 – Compact Size

When designing an IoT device, you won’t have a lot of space on your circuit board. You would need to put the components as close to each other as possible so that your PCB is not too large. IoT devices are usually very compact; hence designers need to produce small designs.  Using proper high density (HDI) design techniques will be a must to ensure the proper PCB integrity.

2- Long Battery Life

Since IoT devices need to be connected to a network at all times and communicate with other devices, they consume a lot of power. As a designer, you must ensure that your design is optimized to make the best use of limited battery capacity.  Low power modes and minimizing parasitic consumption are critical.

Some commonly used batteries that can store charge for a long time are; Button Type Lithium Cells, Lithium Thionyl Chloride Batteries, and Lithium-Ion Batteries. For remote controls and thermostats, you can use AA Alkaline Batteries, Nickel-Cadmium Batteries, and Coin Type Lithium Cells.

3- Minimal Components and Light Weight

PCB designs for IoT projects must have a minimum number of embedded components so that they do not weigh too much. For instance, consider designing an IoT based wristwatch. No one wants to carry a considerable amount of weight on their wrists. So, as a PCB designer, you must make sure that the wristwatch weighs as little as possible so that the person who wears it feels comfortable.

4- Noise Reduction

PCB designs for IoT purposes must be
