“Plug and play” NB-IoT solution targets high volume, low cost applications

German developer grandcentrix says its end-to-end ‘Cellular Twin’ IoT solution is one of the fastest, low cost ways to digitize and network almost any product or application

Nordic Semiconductor tells Incisor that a leading German IoT solution provider, grandcentrix – which is now part of Vodafone – is employing a Nordic nRF9160 SiP at the heart of its high volume, low cost Cellular Twin NB-IoT platform.

Cellular Twin is designed to enable product manufacturers to rapidly digitize their products by transferring telemetry and usage data to the cloud. “With Cellular Twin product manufacturers do not have to invest in risky projects anymore, but can rather make use of a ready-to-go, all-in-one solution,” says Daniel Bracht, a Senior Growth Hacker at grandcentrix.

The hardware of Cellular Twin is a compact, standardized mainboard with optional expansion modules that is designed to turn almost any existing device or product into a smart IoT device by networking it. This includes all required IT, hardware, and in-built connectivity all the way up to native Microsoft Azure IoT support and compatibility with all other major IoT cloud platforms via secure https and MQTT comms.

The mainboard is connected to a product controller via a 15-pin interface and establishes a secure connection to Vodafone’s global NB-IoT M2M cellular network via the integrated Nordic nRF9160 SiP, which also supports over-the-air updates and GPS functionality.

grandcentrix says four digital inputs, four analog inputs (0-10V), and two digital outputs are available on the interface to cover the majority of common industrial applications. And simple analog sensors and digital buttons as well as more complex interfaces such as TTL-UART can also be connected.

And being part of Vodafone has also enabled grandcentrix to build complete SIM management into its Cellular Twin solution to enable seamless international operation and roaming.
