P-NUCLEO-LRWAN1

The P-NUCLEO-LRWAN1 is a 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/or 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 MCU board based on the ultra low power STM32L0 ARM 32bit microcontroller. The I-CUBE-LRWAN is LoRaWAN class A certified.
