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

The STM32 Nucleo pack for LoRaв„ўtechnology and high-performance FSK/OOK RF transceiver modem (P-NUCLEO-LRWAN1) is a development tool to learn and develop solutions based on LoRaв„ўand/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 LoRaWANв„ўnode compliant with class A, based on the Semtech SX1272MB2xAS LoRaв„ў extension board. To control the LoRaв„ў extension board, the pack comes with a NUCLEO-L073RZ MCU board based on the ultra-low-power STM32L0 ARM 32-bit microcontroller. The I-CUBE-LRWAN is LoRaWANв„ўclass A certified.

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