SigFox modules shipped by Arrow Electronics to accelerate IoT development

Compact, low power, XoverIoT-certified Sigfox modules are being shipped by Arrow Electronics. The Sigfox-MOD1-certified modules, created by XoverIoT, help accelerating the development of the IoT, leveraging low-energy Sigfox wireless connectivity.

The modules are available in two versions, the Sigfox-MOD1-C with integrated chip antenna and the Sigfox-MOD1-E with a U.FL socket for an external antenna. The flexibility to dynamically reconfigure for short-range frequency shift keying (FSK) operation or long range communication lets developers create connected solutions to address challengesfor industrial monitoring, asset tracking, supply chain, and smart infrastructure.

XoverIoT’s Sigfox-MOD1 modules are based on the STMicroelectronics Sigfox chipset, which comprises the STM32L051K8 microcontroller, the S2-LPQTR 868MHz radio transceiver and the space-saving BALF-SPI2-01D3 integrated balun.

The module is compact, measuring just 37.6 x 15.0 x 3.8mm. Long battery life is enabled via low power technologies of both the STM32L0 microcontroller and the S2-LP radio transceiver.

The operating current is just 29mA in transmit mode, running off a 3.3V supply. The underlying ST chipset is certified for all Sigfox geographical zones (ZC1 to ZC6).

Modules are supplied loaded with embedded firmware including the Sigfox software stack, which is controlled from the host application using standard AT commands. Alternatively, the microcontroller’s 64kbyte flash can be used to run an application on the module for maximum efficiency and system cost savings, advises Arrow.

A comprehensive set of tools is also available, including the Sigfox-DEV1 Arduino-compatible STM32Nucleo module development kit, Sigfox-CLK1 mikroBUS kit, and Sigfox-USB2 USB dongle for testing module communications with the module.

In conjunction with Arrow, XoverIoT offers additional engineering services to support design-in, antenna design, product approval, and firmware customisation. Access to powerful cloud services, application hosting, and front-end development support can also be provided through trusted partners.
