P-NUCLEO-LRWAN1：Low-power wireless Nucleo pack with Nucleo-L073RZ and LoRa expansion board

The STM32 Nucleo pack for LoRa^®technology and high-performance FSK/OOK RF transceiver modem (P-NUCLEO-LRWAN1) is a development tool to learn and develop solutions based on LoRa^®and FSK/OOK technologies.

This tool, in association with the certified embedded software solution (I-CUBE-LRWAN), provides the means to set up a complete LoRaWAN^™node compliant with class A, based on the Semtech SX1272MB2xAS LoRa^®extension board. To control the LoRa^®extension board, the pack comes with a NUCLEO-L073RZ board based on the ultra-low-power, 32-bit STM32L0 based on ARM^®Cortex^®-M0 microcontroller. The I-CUBE-LRWAN is LoRaWAN^™class A certified.

This pack is the perfect fit for any countries with 868 MHz or 915 ISM frequency bands.
