ESD Warning
Electronic components and circuits are sensitive to
ElectroStatic Discharge (ESD). When handling any
circuit board assemblies including Connect Tech
COM Express carrier assemblies, it is recommended
that ESD safety precautions be observed. ESD safe
best practices include, but are not limited to:
•Leaving circuit boards in their antistatic
packaging until they are ready to be installed.
•Using a grounded wrist strap when handling
circuit boards, at a minimum you should touch a
grounded metal object to dissipate any static
charge that may be present on you.
•Only handling circuit boards in ESD safe areas,
which may include ESD floor and table mats,
wrist strap stations and ESD safe lab coats.
•Avoiding handling circuit boards in carpeted
areas.
•Try to handle the board by the edges, avoiding
contact with components.

INTRODUCTION
Connect Tech’s M.2 GPS is a GNSS receiver based on the very small industry standard M.2 Type-2242-S3-
B form factor. Using the USB bus, the M.2 GPS provides global positioning and time-stamp information,
while taking up little space and power within a system. Also considering the existing support for
Windows and Linux, the M.2 GPS can be easily integrated into any existing system, as well as easily
implemented into new systems.

DETAILED FEATURE DESCRIPTION
USB
The M.2 GPS uses a USB 2.0 Full Speed (12Mb/s) interface as the primary communication bus. The USB
interfaces is connected between the GPS receiver and the M.2 card edge connector (pins 7/9).
TIMEPULSE
The TIMEPULSE output is a buffered and ESD protected signal from the GPS receiver. This signal
connects to pin 2 of the External I/O Connector. It also drives the TIMEPULSE LED. By default, when
satellites are not fixed this signal is High (3.3V). When satellites are fixed, this signal pulses at 1 pulse-
per-second (1Hz) with a 20% duty cycle (200ms High, 800ms Low). For more information see the
Receiver Description Including Protocol Specification document for your GPS receiver found in the
Software Support section of this document.
W_DISABLE1#
The W_DISABLE# input from the M.2 card edge connector (pin 8) can be used to enable and disable
power to the M.2 GPS module. When W_DISABLE1# is low, the module is disabled and no power is
applied to the M.2 GPS. When W_DISABLE1# is High, the module is enabled and powered on. This signal
is locally pulled up to 3.3V through a 100K ohm resistor.
External Interrupt Input/WHEELTICK Input
The external interrupt/WHEELTICK input is an ESD protected input signal from the external I/O
connector to the GPS receiver. On modules that do not support Automotive Dead Reckoning, this signal
will always be an External Interrupt input, and this input can be used for control of the GPS receiver or
for aiding. On modules that support Automotive Dead Reckoning (M2G205/M2G206), this signal is by
default used as the WHEELTICK input and is used to provide speed pulse information to the module. If
the speed pulse information is available from the host processor, then the information can be provided
using software messages in the UBX protocol. If using software messages to provide speed pulse
information, this signal can be configured as an external interrupt input. See the Receiver Description
Including Protocol Specification document for your GPS receiver found in the Software Support section
of this document. If this signal is not used, it should be left floating. Do not exceed 3.6V on this signal.

FWD
The forward/reverse signal is an ESD protected input used on modules that support Automotive Dead
Reckoning. This signal is used to indicate the moving direction of the module. An active high indicates
moving forward and a low for moving backwards. If the forward/reverse information is available from a
host processor, then this information can be provided to the module using software messages in the
UBX protocol. For more information see the Receiver Description Including Protocol Specification
document for your GPS receiver found in the Software Support section of this document. On modules
that do not support Automotive Dead Reckoning, this signal should be left floating. Do not exceed 3.6V
on this signal.
External Battery
The external battery input in an ESD protected input from the External I/O Connector to the backup
voltage supply of the GPS receiver. The purpose of a battery signal is to power internal memory for GPS
almanac, ephemeris, and last position retention through power cycles. The voltage on this input signal
should be greater than 2.0V and less than 3.6V. The supply of this signal should be able to provide at
least 20uA continuous at room temperature, and 50uA at +85 degrees Celsius.
Local Battery and BAT_EN Header
There is a local battery supply on the M.2 GPS. The purpose of a battery signal is to power internal
memory for GPS almanac, ephemeris, and last position retention through power cycles. The design
includes a MS621 rechargeable battery which recharges itself when the unit is powered on. When
power is removed from the unit the GPS receiver will typically consumer 15uA on its battery supply
input at room temperature and 24uA at 85 degrees Celsius.
