Murata Electronics Type ABZ LoRa Modules
Murata Type ABZ LoRa Modules are compact low-power wide-area network (LPWAN) wireless modules that support the LoRaWAN long-range wireless protocol. The modules measure just 12.5x11.6x1.76 mm 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 has joined the LoRa Alliance™, a non-profit association of members who believe that the Internet of Things era is now. Murata has worked to design a cost-effective, small form factor LoRaWAN module capable of supporting a wide range of sensors. This new wireless module should 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
- An ADC and up to 18 GPIOs provide plenty of flexibility for connecting sensors, switches and status LEDs
- Pre-certified radio regulatory approvals for operating in the 868 and 915MHz industrial, scientific and medical (ISM) spectrum in most geographical regions of the world
- The module is powered from a 2.2 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
- An optional STSAFE secure element can be incorporated into the MCU to enhance the network security capabilities
- Operating temperature: -40 + 85°C
Applications
- Smart metering
- Wearables
- Tracking
- M2M and Internet of Things (IoT) edge nodes

WHAT IS "LoRa" and "LoRaWAN"?
LoRa is short for "long-range". It is the physical-layer (PHY) which enables extremely long-range communication with optimised energy efficiency and a robust signal.
LoRaWAN, also known as LPWAN, stands for low-power, wide-area network. It is the global de-factor standard for the Internet of Things (IoT).
LoRaWAN is the foundation of the LoRa Alliance.
