CHAPTER 1 PRODUCT OVERVIEW
6 MultiConnect®Dragonfly TM MTQ-EV3 Device Guide
Chapter 1 – 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 mbedTM compatible software library for faster development. All Dragonfly software is
Open Source.

Note: 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.

MTQ-EV3-B01 External Pin Alternate Function Mapping
This table shows alternate functions available on the external pins of the -B01 models. These functions are
available in mbed and can be redefined by the user. This table also shows which I/O pins are mapped to specific
Arduino shield pins on the MTUDK2-ST-CELL developer board.
Note: For readability, this table has been split into two parts.

Communications Flow
Processor Model (B01)
Note:
The B01 has a UART subset as well as GPIO (4 pin UART (tx/rx/rts/cts)
If needed, use the GPIOs for additional UART signaling.
The USB port can switch between a connection to the radio or a connection to the processor. The
USB selection is controlled via programming on the processor. There is no USB between the radio
and the processor.
No Processor Model (B02)
Note: B02 provides a full UART interface as well as a USB interface.
