STMicroelectronics P-NUCLEO-LRWAN3 STM32 Nucleo Pack

STMicroelectronics P-NUCLEO-LRWAN3 STM32 Nucleo 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 P-NUCLEO-LRWAN3 Pack includes both an LPWAN end-node and its related gateway. The P-NUCLEO-LRWAN3 is compatible with various LoRaWAN^® network server providers. P-NUCLEO-LRWAN3 is intended for countries granting radio-communications access in frequency bands lower than 500MHz.

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. Data coming from the development node can directly reach LoRaWAN network servers. 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 that RisingHF designs 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. Additionally, this expansion board features several sensors from STMicroelectronics: the accelerometer and gyroscope (LSM6DS3), MEMS pressure (LPS22HB), humidity and temperature (HTS221), and magnetometer (LIS3MDL).
