STMicroelectronics P-NUCLEO-LRWAN1 LoRa development kit

Click2Contact

STMicroelectronics has introduced a development kit that leverages the STM32 microcontroller ecosystem for prototyping Internet of Things (IoT) devices with LoRa Wireless Low-Power Wide Area Network (LPWAN) connectivity.

The P-NUCLEO-LRWAN1 kit combines the ultralow-power STM32L073 Nucleo (NUCLEO-L073RZ) microcontroller board with an RF expansion board based on the SX1272 LoRa transceiver from Semtech (I-NUCLEO-SX1272D). The STM32L073 MCU, with its energy-efficient ARM Cortex-M0+ core and ultralow-power features, provides a suitable host for devices such as utility meters, alarm systems, positioning devices, trackers and remote sensors. Users can further extend functionality by adding extra expansion boards, such as the X-NUCLEO-IKS01A1 sensor board, for motion, humidity and temperature sensing.

The kit contains everything needed to build bidirectional end devices that comply with LoRaWAN version 1.0.1 and support class A and class C protocols. Devices can be activated using over-the-air activation (OTAA) or activation by personalisation (ABP). An application for LoRaWAN certification tests is included in the kit.

Access to the STM32 ecosystem provides rich development resources, including STM32Cube tools and software packages containing sample code and hardware abstraction layers (HALs). These allow porting to any of the almost 700 STM32 MCU variants that cover a wide range of performance, power, packages and price points. Developers are also free to use familiar IDEs and ARM mbed online tools.
