The P-NUCLEO-LRWAN1 development kit leverages the STM32 microcontroller ecosystem for prototyping Internet-of-Things (IoT) devices with LoRa Wireless Low-Power Wide Area Network (LPWAN) connectivity. The kit combines the 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 ARM Cortex-M0+ core and proprietary ultra-low-power features, provides a 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 bi-directional 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-Personalization (ABP). Kit price is $40 each. An application for LoRaWAN certification tests is included in the kit, and the I-CUBE-LRWAN LoRaWAN stack is available and posted at http://www.st.com/i-cube-lrwan
