STMicroelectronics and Jorjin Introduce Ultra-Low-Power Sigfox IoT Modules with Dual RF Connectivity

Sigfox-compatible modules from Jorjin integrate STMiicroelectronic’s BLE system-on-chip and sub-1GHz RF transceiver to achieve cost efficiency, high performance, and ultra-low power. A fully programmable modules work as independent IoT nodes with worldwide coverage of Sigfox long-range, low-power wireless network.


STMicroelectronics and Jorjin Technologies have announced the certification of the dual-radio modules that combine Sigfox wireless-network technology with Bluetooth low energy (BLE). Jorjin Technologies is a Taiwan based company established in 1997 to design and supply modules worldwide,

Jorjin’s WS211x Sigfox/BLE modules benefit from the market-leading performance and energy efficiency of ST’s BlueNRG-1 BLE System-on-Chip (SoC) and the S2-LP sub-1GHz RF transceiver. These advantages have enabled Jorjin’s modules to deliver cutting-edge connectivity and great battery lifetime, targeting coin-cell -operated or energy-harvesting IoT applications.

Fully programmable devices, Jorjin’s new Sigfox modules exploit the ultra-low power Arm Cortex- M0 technology embedded in ST’s BLE SoC to act as independent IoT connectivity nodes. The combination of BLE with Sigfox’ low-power wide-area network (LPWAN) provides key benefits to IoT systems, such as firmware update over-the-air, which is not possible with conventional ‘Sigfox-only’ modules.

Other benefits of having an IoT device connected both remotely through the Sigfox network and locally through BLE include the possibility to modify device settings during installation or maintenance or to trace assets, which often change their position inside an area covered with BLE beacon stations.

“We are excited to achieve certification for our first Sigfox-compatible modules,” said Jorjin Technologies chairman Tom Liang. “STMicroelectronics and Sigfox teams’ support has been very helpful and we are looking forward to keeping expanding our collaboration with both partners.”

“The successful certification marks a significant milestone in our cooperation with Jorjin, delivering high-performance, ultra-low-power dual-radio Sigfox modules,” said Maria Rosa Borghi, Low Power RF BU Senior Director, Analog, MEMS and Sensors Group, STMicroelectronics. “Designers now get a cutting-edge solution for building high-mobility products with versatile connectivity and low power budget across all IoT segments.”

“We are glad to welcome Jorjin to our ever-expanding ecosystem and to partner once again with ST for the acceleration of the adoption of the IoT among the different verticals. The certification of the Jorjin module will allow us to boost the production of Sigfox-enabled devices answering a growing demand from our clients,” said Raouti Chehih, Sigfox Chief Adoption Officer.

The evaluation board for the WS211x modules uses the Arduino interface to ease customer development and is compatible with ST’s Arduino shield boards featuring MEMS motion sensors, environmental sensors, or Time-of-Flight (ToF) ranging sensors. An SDK is available from Jorjin enabling customers to develop applications using WS211x modules with ST’s sensor shield boards, as well as an AT command list facilitating customers test of the modules’ BLE and Sigfox functions.
