MG - I-NUCLEO-LRWAN1

Description

USI® in cooperation with STMicroelectronics developed the LoRa® expansion board for STM32 Nucleo (I-NUCLEO-LRWAN1). This board is an integrated solution that enables everyone to learn and develop solutions using LoRa® and / or FSK / OOK technology.

I-NUCLEO-LRWAN1 is equipped with the USI® LoRaWAN ™ technology module, addressing low-cost and extensive LAN with low power consumption (LPWAN), which is delivered with a built-in AT command stack.

The I-NUCLEO-LRWAN1 device can be controlled from an external host, for example from NUCLEO-L053 cards, with the I-CUBE-LRWAN software installed. This software provides means to configure a complete LoRaWAN ™ node.

I-NUCLEO-LRWAN1 is Class-A LoRaWAN ™ certified and maintains Class C.

I-NUCLEO-LRWAN1 includes the USI® LoRaWAN ™ module, Arduino ™ connectors, SMA connector, 50 Ω antenna and three ST environmental sensors.
