P-NUCLEO-LRWAN1 Nucleo-L073RZ Development Board and LoRa Expansion Kit

The STM32 Nucleo set for LoRa® technology and high-performance FSK/OOK RF transceiver modem (P-NUCLEO-LRWAN1) serves as a development tool for learning and creating solutions based on LoRa® and FSK/OOK technologies.

This tool, in conjunction with a certified embedded software solution (I-CUBE-LRWAN), provides the means to set up a complete LoRaWAN™ Class A node based on the Semtech SX1272MB2xAS LoRa® expansion board. For controlling the LoRa® expansion board, the kit includes the NUCLEO-L073RZ board which is based on the 32-bit STM32L0 microcontroller with ultra-low power consumption employing the ARM® Cortex®-M0 architecture. The I-CUBE-LRWAN has been certified for LoRaWAN™ Class A.

This package is perfectly suited for all countries with a frequency range of 868 MHz or 915 ISM.
