MTQ-LVW3 Device Guide

Chapter 1 – Chapter 1 Product Overview

Overview

The Dragonfly

TM

(MTQ) cellular system-on-module (SoM) is a ready-to-integrate processing and communications

device that offers developers the functionality of a SoM with the convenience of an onboard cellular radio all in
one compact design. Models with the integrated ARM

®

Cortex

®

-M4 processor allow developers to host their

application and have access to a full suite of interfaces for connecting sensors or other remote assets. Dragonfly
features an ARM mbed

TM

compatible software library for faster development. All Dragonfly software is Open

Source.
