23-05-2022 | Wurth | Subs & Systems

Würth Elektronik offers the Adrastea-I, its high performance, ultra-low power consumption, multi-band LTE-M and NB-IoT module. This cellular module, measures just 13.4mm × 14.6mm × 1.85mm, has integrated GNSS, integrated ARM Cortex M4 and 1MB Flash reserved for user application development. The module is based on the high-performance Sony Altair ALT1250 chipset. Certified by Deutsche Telekom, the module provides swift integration to end-products with no additional labels, industry-specific certifications (GCF) and operator approvals required, whenever Deutsche Telekom IoT connectivity (SIM card) is utilised. The module is excellent 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 allows the support for international, multi-regional coverage, such as wherever LTE-M does not have coverage, it can be configured to employ NB-IoT instead, and vice versa. The module is 3GPP Release-13 compliant, upgradable to Release-14. The module is optimised for ultra-low power consumption, compact size, and enhanced coverage. Its small dimensions make it an ideal fit for size-constrained applications such as wearables.

The module has integrated GNSS, supporting GPS and GLONASS satellite systems. Integrated GNSS make it ideal for asset tracking applications where infrequent position updates are needed.

“With the introduction of the Adrastea-I radio module and IoT SIM cards from Deutsche Telekom, we are excited to offer a complete cellular solution. The integrated MCU exclusively for customer application development, enables engineers to design exceptional products and services using LTE-M and NB-IoT cellular technology. The pre-certified Adrastea-I module from Deutsche Telekom enables a quick integration to end-products, saving development costs and shortening time to market. Despite the worldwide shortage of components, Adrastea-I and its evaluation kit are available in stock,” says Ravindra Singh, product manager, at Würth Elektronik eiSos.

“We are pleased to certify the Adrastea-I module from Würth Elektronik eiSos for our multiple NB-IoT and LTE-M networks. By completing our certification processes, we ensure a best-in-class connectivity and excellent performance for our customers,” said Uday Patil, head of IoT Devices, T-Systems International GmbH. “The Adrastea-I is a strong addition to our portfolio of operator-certified IoT cellular modules, one the largest worldwide.”
