Chapter 1 – Product Overview
Overview
The Dragonfly
TM
Nano (MTQN) cellular System-on-Module (SoM) is a small version of the Dragonfly (MTQ) System-
on-Module (SoM). Both embedded devices offer developers the functionality of an on-board cellular radio all-in-
one compact design. The Dragonfly Nano provides a practical solution to the market's demand for a smaller, low-
power module.
The Dragonfly Nano functions similarly to the Dragonfly and maintains interoperability with legacy systems that
use a 40-pin connector and forward mounting hole. All Dragonfly software is open source.

Switching between the USB interface and serial port requires a reset. The cellular radio checks for a USB
connection upon reset. If USB is not present, it only uses the serial port. If USB is present upon reset, it only uses
USB.

values.
(3) This formula has to be applied only on the power supplies related to the IO structure described in the pin
definition table.
(4) To sustain a voltage higher than 4 V the internal pull-up/pull-down resistors must be disabled.
(5) Include VREF- pin.

) and ground (V

power, in permitted range.
(2) This current consumption must be correctly distributed over all I/Os and control pins. The total output current
must not be sunk/sourced between two consecutive power supply pins referring to high pin count QFP packages.
(3) Positive injection (when V

> V

) is not possible on these I/Os and does not occur for input voltages lower
than the specified maximum value.
(4) A negative injection is induced by V

must never be exceeded. Refer to the Absolute Maximum
Ratings table for the minimum allowed input voltage values.
(5) When several inputs are submitted to a current injection, the maximum Σ|I

negative injected currents (instantaneous values).

Maximum Power: The continuous current during maximum data rate with the radio transmitter at maximum
power.
2
Tx Pulse: The average peak current during a GSM 850 transmission burst period or LTE connection. The
transmission burst duration for GSM 850 can vary, depending on what transmission scheme is being deployed
(GPRS Class 8, Class 10, GSM, etc.).
3
Inrush Charge: The total inrush charge at power on.
USB Cable Recommendations
If your device has a USB connector, to avoid enumeration or power issues:
Use a high-speed USB cable that is as short as possible.
Use a well-shielded cable with at least 24 AWG wire pair for power/ground and 28 AWG wire pair for data
lines.
If possible, use a USB port that connects directly to the motherboard rather than a USB port with added
cabling inside the computer chassis.
Use USB 3.0 ports if available. These ports are typically rated for more current.
