Murata has launched a compact low cost low power wide area network (LPWAN) wireless module that supports the LoRaWAN long range wireless protocol.
This stand-alone compact module measures just 12.5 x 11.6 x 1.76 mm, is constructed in a metal shielded package and comprises a Semtech SX1276 ultra long range spread spectrum wireless transceiver covering worldwide frequencies and an STMicroelectronics STM32L0 series ARM Cortex M0+ 32 with 192Kbytes Flash memory. An integrated TCXO that has robust low drift thermal characteristics provides an accurate clock source for the RF transceiver. To increase product and network security, the module embeds a secure element (optional).
The Murata CMWX1ZZABZ-078 module has pre-certified radio regulatory approvals for operating in the 868 and 915 MHz industrial, scientific and medical (ISM) spectrum in most geographical regions of the world.
The normal output power is + 14 dBm but a PA boost function can be selected to increase RF output to + 20dBm for long range applications or those where the end-device is sited in a poor signal location indoors.
The on-board STMicroelectronics MCU includes 192 kB flash and 20 kB RAM, and has enough memory to embed customer applications and host other modulation stacks. In addition, an optional STSAFE secure element can be incorporated into the MCU to enhance the network security capabilities.
Typical applications for this module include smart metering, wearables, tracking, M2M and internet of things (IoT) edge nodes. Accommodating a wide range of temperatures, the module can operate from –40 to +85 °C.
The Murata CMWX1ZZABZ-078 LoRa module is supported by the B-L072Z-LRWAN1 LoRa Discovery Kit from STMicroelectronics, click here to learn more and register your interest for a FREE Discovery Kit
