The two packs are designed to operate at two different frequency bands; the P-NUCLEO-LRWAN2 pack  uses the high-frequency (868MHz/915MHz/923MHz) ISM bands for use in countries granting radio-communications access in frequency bands higher than 800 MHz and  the P-NUCLEO-LRWAN3 pack covering the low-frequency (433/470MHz) ISM bands. Both packs include a complete LoRaWAN toolchain with gateway and end node boards, firmware and tools based on the Nucleo STM32 evaluation boards from STM.
 
The LoRa gateway used by both packs is based on the STM32 Nucleo-144 development board with an STM32F746ZG MCU which supports Arduino, ST Zio and morpho connectivity. The morpho headers give full hardware access to all the STM32 I/Os for maximum flexibility. To enable users to use basic network server functions free of charge, ST has signed contracts with the LoRaWAN network server providers LORIOT, Actility and The Things Network. Using the drag and drop IoT project builder myDevices Cayenne for LoRa, you build projects, show sensor measurement data and provide control of devices.
 
Both of the sensor nodes uses the NUCLEO-L073RZ, based on an ultra-low-power STM32L0 Arm 32-bit microcontroller, to control a USI I-NUCLEO-LRWAN1 Arduino expansion board. The board is also equipped with a whole raft of motion and environmental sensors.

The two versions are priced at $99 and include the on-board debugger, antennae, gateway, node and firmware.
