Multistack LPWAN kit eases smart city design applications

29-12-2020 | Murata | Design & Manufacture

Murata, together with Sentinum, has launched a multistack development kit for LPWAN implementations. The Yamori dev kit offers an array of wireless modules from the company’s extensive portfolio to speed evaluation activity. This enables various IoT-related LPWAN application criteria to be addressed through a single multifaceted platform that is unique in the industry. The following RF and cellular protocols have been incorporated: LoRa, NB-IoT, Cat M1 (LTE-M) and voice over LTE (VoLTE). Also, NFC connectivity and GNSS functionality are encompassed, and Sigfox and MIOTY can be helped by a simple firmware upgrade.


Within a 63mm x 29.3mm x 40mm 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 are also included, as well as printed antennas, to offer engineers a fully-integrated IoT development resource. Low power operation assures that battery life is lengthened, with as low as 1.5μA (cellular mode) being drawn when in hibernation mode. By utilising the kit, designers can create solutions that produce elevated performance parameters while using little space and taking minimal power. Smart parking, environment monitoring, building automation, asset tracking, industrial control, smart agriculture, smart metering and emergency service response are just a few of the diverse uses that this kit can be employed 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,” states 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.”
