SAM R34 MLS Getting Started Guide

Introduction

The Microchip LoRaWAN

™

Stack (MLS) provides a solution for the LoRaWAN end-device that is used for

Internet of Things (IoT) applications.

LoRa

is a wireless modulation technique designed to allow low-power end-devices to communicate over

long range and at low data rates.

LoRaWAN is a wireless networking protocol which operates over LoRa communication layer and acts as

Medium Access Control (MAC) layer.

LoRaWAN specification and its development is overseen by LoRa Alliance

™

. The specification is meant

for secure communication of end-devices and ensures inter-operability within the LoRa network.

Features

• Low-Power LoRaWAN Solution

• SAM R34 SiP Based on Low Power ARM M0+ Core

• Application Integration Ready

• Persistent Data Server (PDS)

• Power Management Module (PMM)

• Dynamic Regional Band Selection Support
