What Makes Nordic nRF Microcontrollers a Strong Fit for Industrial IoT

I have worked with a variety of microcontrollers for IoT applications and some major concerns are power consumption and size.
Given that the microcontroller is just a part of this system, other peripherals attached to it add to this concern. Each component connected contributes to PCB complexity and power draw.

When I started working with Nordic nRF microcontrollers, the thing that struck me first was how much they collapse alot of peripherals into a single chip. The major ones being a wireless transceiver, a power management unit and a crypto chip. For industrial sensor nodes that need to be physically small and run for years on a battery, that integration is not just convenient, it's the difference between a viable product and a prototype that never ships.

Industrial IoT specifications and requirements

Apart from size and power consumption, Nordic nrf microcontrollers fit into the requirements and framework of IIoT infrastructure -  ITU-T Y.4228 (08/2024).

The framework organises IIoT infrastructure into three layers: the Device Layer at the bottom — sensors and gateways — the Network Layer in the middle, and the Service Support and Application Support Layer at the top, which covers cloud computing, data processing, and enterprise systems.

Nordic nRF microcontrollers operate primarily in the Device Layer. They are the sensors and the gateway nodes. Through the wireless protocols integrated into the mcu — BLE, Bluetooth Mesh, Thread, LTE-M, and NB-IoT — they reach up into the Network Layer, connecting the physical world to the enterprise and cloud infrastructure above.

Just as a by the way, Nordic Semiconductor recently acquired memfault which is the market-leading cloud platform provider for large-scale deployments and device management of connected products. This streamlines the product life-cycle of IIOT devices developed using nordic nrf microcontrollers.

What Else?

Zephyr is the answer to this question. The Nordic nrf families of mcus use Zephyr as the default operating system.
Alot of information is already out there about zephyr so on my end I will only mention its use in industrial iot applications. For that you will have to attend my session at the Embedded Online Conference 2026

Getting Started

If you're interested in exploring the Nordic nRF ecosystem, you can join me in my session at the Embedded Online Conference 2026. I go further into the SOC and families of nordic nrf microcotrollers. A deep dive into bluetooth implementation and application on the boards. A mention of other wireless protocols used and a live walkthrough of setting up the development toolchain.

If you've been considering Nordic nrf for an upcoming project but aren't sure where to begin, that walkthrough should get you from zero to a working environment in one sitting.
