Murata, in cooperation with technology partner Sentinum, has introduced a multistack development kit for low-power wide area network (LPWAN) implementations. The Yamori dev kit features an array of wireless modules from Murata’s expansive portfolio to accelerate evaluation activity. This allows various IoT-related LPWAN application criteria to be addressed via a single multifaceted platform.

The following RF and cellular protocols have been included: LoRa, NB-IoT, Cat M1 (LTE-M) and voice over LTE (VoLTE). In addition, NFC connectivity and GNSS functionality are also encompassed and Sigfox and MIOTY can be supported by a simple firmware upgrade.

Within a 63x29mm and 30x40mm form factor, Yamori houses an ultra-compact LBAA0QB1SJ LoRa module, and an LBAD0XX1SC cellular module. A Murata CR3677X Lithium coin battery and CT04120 secondary battery have also been incorporated, along with printed antennas, in order to present engineers with a fully-integrated IoT development resource. Low power operation ensures that battery life is prolonged, with as low as 1.5μA (cellular mode) being drawn when in hibernation mode.

By using the kit, designers can develop solutions that deliver elevated performance parameters, while taking up little space and consuming minimal power. Smart parking, environment monitoring, smart agriculture, building automation, asset tracking, industrial control, smart metering and emergency service response are just some of the diverse use cases that this kit can be used for.

“By working with Sentinum, we have been able to bring a game-changing prototyping platform to market. It provides engineers with all the building blocks upon which innovative LPWAN solutions can be implemented,” said Koichi Sorada, Product Manager of the IoT Connectivity Europe team at Murata. “No time is wasted with the integration of peripheral elements, such as antennas or a power source, since these are already included. Consequently, it is possible to move through the prototyping phase within a much shorter timeframe. Furthermore, design concepts can be adapted, rather than having to start new projects from scratch.”
