Compact LoRaWAN module offers low-power, application-ready platform
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⢠LBAA0QB1SJ 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 oscillatorÂ
- Multiple communication interfacesÂ
- 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 ÂľA, often extending the life of a single battery to many years.
The module has RF certification for most regions of the world.
