Murata Electronics ABZ LoRa® Modules
Murata ABZ LoRa® Modules are compact low-power wide-area network (LPWAN) wireless modules that support the LoRaWAN long-range wireless protocol. These modules measure only 12.5mm x 11.6mm x 1.76mm and are housed in metal-shielded packages. The modules include a Semtech SX1276 ultra-long-range spread spectrum wireless transceiver and an STMicro STM32L0 series Arm® Cortex® M0+ 32-bit microcontroller (MCU).
Murata is a member of the LoRa Alliance™, a nonprofit association that fully supports the Internet of Things (IoT). Murata has designed a cost-effective, small-form factor LoRaWAN module capable of supporting a wide range of sensors. These wireless modules will help increase the adoption of the LoRaWAN platform worldwide and make it the standard for LPWANs supporting low-power IoT applications.
Features
- Integrated TCXO with robust low drift thermal characteristics provides an accurate clock source for the RF transceiver
- ADC and up to 18 GPIOs offer flexibility for connecting sensors, switches, and status LEDs
- Pre-certified radio regulatory approvals for operating in the 868MHz and 915MHz industrial, scientific, and medical (ISM) spectrum in most geographical regions of the world
- Module is powered from a 2.2VDC to 3.6VDC supply
- MCU includes 192kB flash and 20kB RAM
- Normal output power is +14dBm, but a PA boost function can be selected to increase RF output to +20dBm for long-range applications
- Communication with the module can be achieved via UART, SPI, or I2C peripheral interfaces
- Optional STSAFE secure element can be incorporated into the MCU to enhance the network security capabilities
- -40°C to +85°C operating temperature range
Applications
- Smart metering
- Wearables
- Tracking
- M2M and IoT edge nodes

What is LoRa & LoRaWAN?
LoRa is short for "Long Range." It is the physical layer (PHY) that enables extremely long-range communication with optimized energy efficiency and a robust signal. LoRaWAN, or LPWAN, stands for low power, wide area network. It is the global standard for IoT. LoRaWAN is the foundation of the LoRa Alliance.
