PRODUCT OVERVIEW
Chapter 1 – Product Overview
Overview
The MultiConnect®DragonflyTM(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 mbedTMcompatible software library for faster development. All Dragonfly software is
Open Source.

mbed has limited USB support for the processor. Software controls routing to processor or directly to radio.
2
The battery management circuit is designed for single cell Li-Ion/Li-Poly technology. Acceptability of the battery
charge circuit for charging specific batteries/cells is to be determined in the end product.
3
Radio performance may be affected by temperature extremes. This is normal.
4
Device has been tested up to +85° C. UL Recognized @ 85° C.
Note: Acceptability of the battery charge circuit for charging specific batteries/cells is to be determined in the
end product.
Powering Down Your Device
CAUTION: Failing to properly power down the device before removing power may corrupt your device's file
system.
To properly power down your device, use the following sequence or pull 3G_ONOFF signal low:
1. Issue the AT#SHDN command.
2. Wait 30 seconds.
3. Power off or disconnect power.
Note: If you send AT#SHDN and do not remove power AND the 3G_ONOFF line is high, the radio restarts after
60 seconds.

For -B02 models only: Pins 14, 15, 16, and 27 are part of the SPI interface. These pins are inputs. If you do not use
them, connect them externally to a high level signal (preferably through a high pull-up resistor) to keep them from
floating.
