STMicroelectronics has introduced a low-cost 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.
 
Priced at $40, the P-NUCLEO-LRWAN1 kit combines the ultra-low-power STM32L073 Nucleo (NUCLEO-L073RZ) microcontroller board with an RF expansion board based on the proven SX1272 LoRa transceiver from Semtech (I-NUCLEO-SX1272D). The STM32L073 MCU, with its energy-efficient ARM Cortex-M0+ core and proprietary ultra-low-power features, provides an ideal host for devices such as utility meters, alarm systems, positioning devices, tracker 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.
 
LoRa enables long-range communication with several advantages over conventional cellular connections, including lower power and cost.
