STMicroelectronics’ Sigfox™ Embedded Software for STM32 Microcontrollers Boosts Connectivity Choices for IoT-Device Developers

STMicroelectronics has extended its STM32 software ecosystem with a Sigfox™ package that simplifies development and gives extra flexibility to connect Internet-of-Things (IoT) devices to long-range, low-power wireless networks.

The new X-CUBE-SFOX package is ready to use with ST’s B-L072Z-LRWAN1 Discovery Kit, which is already LoRa™ enabled through I-CUBE-LRWAN embedded software. Developers can now work with either of these established Low-Power Wide Area Network (LPWAN) technologies on the same hardware, and create products that can use the two protocols individually or alternatively. The Discovery Kit features the Murata CMWX1ZZABZ-091 module powered by an STM32L072 microcontroller, a sub-GHz radio transceiver SX1276 from Semtech, and is expandable via Arduino headers to add sensors or other IoT-device functions and capabilities.

X-CUBE-SFOX contains a complete set of Sigfox libraries and application examples for the STM32L0, and can be ported to other microcontrollers in the STM32 family. With over 700 STM32 variants, from ultra-low-power to high-performance lines, developers can leverage unrivaled flexibility to optimize the performance and features of IoT devices that take advantage of Sigfox services including basic connectivity, radio recognition, and GPS-free location. The software’s low memory footprint and efficient CPU utilization minimize demand for system resources, helping to lower bill-of-materials (BOM) costs and power consumption.

The X-CUBE-SFOX software can be downloaded free of charge from www.st.com/x-cube-sfox. The B-L072Z-LRWAN1 Discovery Kit is available now, priced $46.50.

Notes to Editors:
Sigfox networks now cover a total of 3.2 million square kilometers of the earth’s surface and are active in 36 countries, with national coverage in 17 of these. ST’s Sigfox stack, included in the X-CUBE-SFOX package, is already certified for international zones 1, 2, and 4, thereby streamlining product testing and approval for territories including 27 EU countries, Oman, South Africa, Iran, Kenya; US, Brazil, Mexico, Canada; Colombia, Peru, New Zealand, Australia, Singapore, and Taiwan.
