    The P-NUCLEO-LRWAN2 STM32 Nucleo starter pack for LoRa® technology and high-performance (G)FSK/OOK/(G)MSK modulations is a development tool to learn and quickly develop low-power wide-area network (LPWAN) solutions. The pack contains both an LPWAN end-node and its related gateway. It is compatible with various LoRaWAN® network server providers. P-NUCLEO-LRWAN2 is intended for countries granting radio-communications access in frequency bands higher than 800 MHz.


    On the gateway side, the NUCLEO-F746ZG board, based on a high-performance STM32F7 Arm® 32-bit microcontroller, controls a RisingHF ARDUINO® expansion board (LRWAN_GS_HF1) used as a basic LoRaWAN® packet forwarder. In that way, data coming from the development node can reach LoRaWAN® network servers directly.


    On the sensor-node side, the NUCLEO-L073RZ, based on an ultra-low-power STM32L0 Arm® 32-bit microcontroller, controls a USI® I-NUCLEO-LRWAN1 ARDUINO® expansion board used as a sensor node.


    The I-NUCLEO-LRWAN1 end-node is an ARDUINO® compatible expansion board. This board is designed by USI® around a LoRa® module powered by an STM32L05 device hosting a friendly AT command stack. This makes user development and access to the LoRa® technology easier. In addition, this expansion board features several sensors from STMicroelectronics: accelerometer and gyroscope (LSM303AGR), MEMS pressure (LPS22HB), and humidity and temperature (HTS221).
