The I-NUCLEO-LRWAN1 can be controlled from
an external host such as NUCLEO-L053 boards,
running the I-CUBE-LRWAN embedded software.
This software provides the means to set up a
complete LoRaWAN™ node.
The I-NUCLEO-LRWAN1 is LoRaWAN™ class A
certified and sustains the class C.
The I-NUCLEO-LRWAN1 includes the USI
®
LoRaWAN™ module, Arduino™ connectors, a
SMA connector, a 50
Ω
antenna and three ST
environmental sensors.
For more details about all the components of the
LoRa
®
-Middleware library, refer to the
STM32
LoRa
®
software expansion for STM32Cube
user
manual (UM2073).
The I-NUCLEO-LRWAN1 is supplied by a third
party not affiliated to ST. For complete and latest

Description
USI
®
in partnership with STMicroelectronics
developed the LoRa
®
expansion board for STM32
Nucleo (I-NUCLEO-LRWAN1). This board is an
integrated solution allowing anyone to learn and
develop solutions using LoRa
®
and/or FSK/OOK
technologies.
The I-NUCLEO-LRWAN1 features the USI
®
LoRaWAN™ technology module, addressing low-
cost and low-power wide area network (LPWAN),
which comes with the embedded AT-command
stack pre-loaded.
