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.
