Introduction

This user manual describes the I-CUBE-LRWAN LoRaWAN

®

Expansion Package implementation on the STM32L0 Series,

STM32L1 Series, and STM32L4 Series microcontrollers. This document also explains how to interface with the LoRaWAN

®

to

manage the LoRa

®

wireless link.

LoRa

®

is a type of wireless telecommunication network designed to allow long-range communications at a very low bit-rate

The I-CUBE-LRWAN main features are the following:

• Integration-ready application

•

Easy add-on of the low-power LoRa

®

solution

• Extremely-low CPU load

• No latency requirements

• Small STM32 memory footprint

• Low-power timing services provided

The I-CUBE-LRWAN Expansion Package is based on the STM32Cube HAL drivers (Refer to LoRa standard overview).

• P-NUCLEO-LRWAN2, STM32 Nucleo starter pack (USI

• P-NUCLEO-LRWAN3, STM32 Nucleo starter pack (RisingHF) for LoRa

• B-L072Z-LRWAN1, STM32 Discovery kit embedding the CMWX1ZZABZ-091 LoRa

module from Murata

• I-NUCLEO-LRWAN1, LoRa

®

expansion board for STM32 Nucleo, based on the WM-SG-SM-42 LPWAN module (USI

®

)

available in P-NUCLEO-LRWAN2

• LRWAN-NS1, expansion board featuring the RisingHF modem RHF0M003 available in P-NUCLEO-LRWAN3

The I-CUBE-LRWAN Expansion Package runs on STM32 32‑bit microcontrollers based on the Arm

®

®

-M

processor.
