LoRaWAN™ Wireless Module

Murata's LoRaWAN wireless module capable of supporting a wide range of sensors

Image of Murata's LoRaWAN Wireless ModuleMurata's 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 mm x 11.6 mm x 1.76 mm, is constructed in a metal shielded package, is rated for -40°C to +85°C, comprises a Semtech SX1276 ultra-long range spread spectrum wireless transceiver, and an STMicro STM32L0 series ARM® Cortex®-M0+ 32-bit microcontroller (MCU). An integrated TCXO that has robust low drift thermal characteristics provides an accurate clock source for the RF transceiver.

Communication with the module can be achieved via UART, SPI, or I2C peripheral interfaces. An ADC and up to 18 GPIOs provide plenty of flexibility for connecting sensors, switches, and status LEDs. The module is powered from a 2.2 VDC to 3.6 VDC supply. The Murata CMWX1ZZABZ-078 module has pre-certified radio regulatory approvals for operating in the 868 MHz 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 +20 dBm for long range applications or those where the end-device is sited in a poor signal location indoors.

The 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.
