Würth Elektronik Adrastea-I LTE-M and NB-IoT module

Würth Elektronik presents the Adrastea-I, its high-performance, ultralow power consumption, multi-band LTE-M and NB-IoT module. The cellular module, measuring 13.4 x 14.6 x 1.85 mm, comes with integrated GNSS, integrated ARM Cortex M4 and 1 MB Flash reserved for user application development. Based on the high-performance Sony Altair ALT1250 chipset, the module is suitable for Industrial IoT, smart agriculture, smart logistics and smart metering applications.

The module has multi-band support and can be operated through one of two (LTE-M and NB-IoT) cellular communication technologies. This enables support for international, multi-regional coverage; for example, wherever LTE-M does not have coverage, the product can be configured to use NB-IoT instead, and vice versa. Its integrated GNSS supports both GPS and GLONASS satellite systems; integrated GNSS makes it suitable for asset-tracking applications where infrequent position updates are required.

The module is 3GPP Release-13 compliant, upgradable to Release-14. It is optimised for ultralow power consumption, compact size and enhanced coverage. Its small dimensions make it suitable for size-constrained applications such as wearables.

The module’s integrated ARM Context M4 MCU, 1 MB Flash and 256 KB RAM are available exclusively for user application development. Sony Altair provides a software development kit (SDK), sample code examples, documentation and tools to accelerate innovation and product development on the integrated ARM Cortex M4 MCU.
