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.

REVISION HISTORY

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.
