P-NUCLEO-LRWAN3 STM32 Nucleo pack LoRa™ LF band sensor and gateway

The P-NUCLEO-LRWAN3 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-LRWAN3 is intended for countries granting radio-communications access in frequency bands lower than 500 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_LF1) used as a basic LoRaWAN^® packet forwarder. In that way, data coming from the development node can directly reach LoRaWAN^® network servers.
On the sensor-node side, the NUCLEO-L073RZ, based on an ultra-low-power STM32L0 Arm^® 32-bit microcontroller, controls a RisingHF LRWAN_NS1 ARDUINO^® expansion board used as a sensor node.
The LRWAN_NS1 end-node is an ARDUINO^® compatible expansion board. This board is designed by RisingHF around a LoRa^® module powered by an STM32L07 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 (LSM6DS3), MEMS pressure (LPS22HB), humidity and temperature
