STMicroelectronics has expanded its narrowband cellular portfolio with two new NB-IoT modules and an upgraded development ecosystem, aiming to make it easier for manufacturers to design connected devices for industrial, consumer, and public-sector applications.
The Geneva-based semiconductor group on 17th November unveiled refreshed versions of its ST87M01 module family, already widely used in European smart-meter deployments. The latest devices add optional geolocation features and are supported by an extended suite of development tools, including an evaluation kit, software, and third-party integration support.
“We are now taking the next step to make our module technology and fully owned, resilient supply chain accessible across a wider variety of markets and environments,” said Domenico Arrigo, General Manager of the Application Specific Analog Product Division. He added that the modules combine compact size, low power use, reliability, and security to enable “scalable and secure IoT deployments”.
The new line-up includes the ST87M01-1001, which provides NB-IoT connectivity, and the ST87M01-1301, which adds GNSS and Wi-Fi positioning for indoor and outdoor tracking. Both are supported by the EVKITST87M01-2 evaluation kit, which bundles a Conexa IoT SIM, two antennas, and tools for prototyping real-world NB-IoT applications.
Developers can also use ST’s Easy-Connect software library, which provides a hardware-agnostic interface for configuring NB-IoT, GNSS, and Wi-Fi functions and transferring data over cellular networks. The bundled Conexa SIM, provided by ST Authorised Partner Wireless Logic, includes 50MB of data valid for six months and is configured for the EMEA region.
“Wireless Logic’s cellular connectivity, included free of charge with ST’s latest NB-IoT module evaluation kits, provides the easiest and fastest way to connect and develop prototypes,” said John Dillon, Product and Marketing Managing Director at the company. He said the Conexa network provides wide geographical coverage and resilient NB-IoT service.
ST has partnered with other specialists to speed commercial deployment. Ignion supplies Virtual Antenna components and its Oxion AI-driven design platform, which helps engineers select and integrate antennas. “Our Virtual Antenna and Oxion platform make RF design simpler, faster, and more predictable,” said CEO Jaap Groot.
Italian firm DAOS will offer optional design and manufacturing support, covering hardware, software, and production. “We are proud to support ST’s customers with our in-depth expertise and commitment to deliver reliable IoT technologies,” said CEO Andrea Lombardo.
ST will showcase the two new modules at Enlit Europe 2025 in Bilbao from 18th–20th November, demonstrating applications including connected water metering, smart street lighting, asset tracking, and a version paired with the ST4SIM-300 eSIM for secure connectivity.
