Compact LoRaWAN module offers low-power, application-ready platform

Murata

The Murata Type 1SJ module is a complete system including LoRaWAN radio, 32-bit microcontroller, memory, and system communications interfaces, giving designers a fast and easy way to implement low-power, wide-area networking

The Type 1SJ LoRaWAN™ module from Murata is suitable for a wide range of high-volume applications in which small size, long range, extended battery life, security, and a competitive price point are requirements.

 

Measuring just 10.0 mm x 8.0 mm x 1.6 mm, the Type 1SJ is based on a second-generation Semtech SX1262 LoRaWAN radio chip, and an STM32L072 microcontroller from STMicroelectronics on which developers can run their application software. The module, which has the part number LBAA0QB1SJ, also includes:

  • RF switch
  • 192 kbytes of Flash memory and 20 kbytes of RAM
  • Temperature-controlled crystal oscillator
  • Multiple communication interfaces
  • Various GPIOs

 

The module supports ISM bands between 868 MHz and 916 MHz, including those used in Europe, the US, India, and countries in the Asia-Pacific region.

Operating from a single supply rail up to 3.9 V, the Type 1SJ module offers several low-power modes that allow the real time clock to operate while drawing a typical current of just 1.3 µA, often extending the life of a single battery to many years.

The module has RF certification for most regions of the world.

Features

  • Performs LoRa and FSK signal modulation
  • 118 mA Transmit current at 22 dBm
  • 5mA Receive current at 125 kHz bandwidth
  • -135.5dBm receiver sensitivity
  • External antenna
  • I2C/UART/USB/serial peripheral interfaces
  • Operating-temperature range: -40°C to 85°C

Applications

  • Smart metering
  • Wearable devices
  • Asset tracking
  • Machine-to-machine communication
  • IoT edge nodes
  • Smart agriculture
  • Building automation
  • Smart cities
Murata — Type 1SJ LoRaWAN Module

Evaluation Kit

Part Number: LBAA0QB1SJ-TEMP-EVK 

This kit enables engineers to evaluate the operation and characteristics of the Type 1SJ low-power wide-area networking module. The module can modulate signals for both the LoRaWAN™ and FSK modulation protocols.

 

The board includes an ST-LINK/V2-1 embedded debug tool interface, LEDs, push buttons, an antenna, Arduino™ Uno V3 connectors, and a USB On-The-Go connector in Micro-B format.

 

The kit is supported by a Murata software development kit, which is available for download from the Murata customer online portal.
