5 User Interface
M-90 provides 2-wire digital UAR port for communication of GPS position
data using NMEA protocol or M K extension protocol. UAR port is capable of
4800 to 115200 baud rate.
5.1 Protocol
M-90 is default to support standard NMEA-0183 protocol. In addition, a series
of M K extensions (PM K messages) have been developed that can be used
to provide extended capabilities common to many applications
5. NMEA Protocol
M-90 is capable of supporting following NMEA formats:
NMEA RECORD Description
GGA GPS fix data
GLL Geographic
GSA GNSS DOP and active satellite
GSV GNSS Satellites in view
RMC Recommended minimum specific
GNSS data
VTG Course Over Ground and Ground

receiving sensitivity, a low noise amplifier with 19dB gain and 1.8dB noise
figure is suggested to designed in mother board or active antenna.
U3:Silicon Labs SP3223EEA, which is a RS232 IC.

Block1: he LNA environment parameter is possibly different between M-90
and the mainboard, please notice and fine tune if possible.
Block : User can supply the low power to pin “HRS ” if you want to reset GPS,
or keep the pin as “pull high” or “floating” in operating.

Block3: User can supply the high power to pin “PWR_EN” to enable module or
supply the low power to pin “PWR_EN” to disable module.
Block4: For user’s convenience, M-90 sends the signal once per second from
1pps pin, he output is a CMOS 2.8V positive level signal which is
synchronous with GPS time within 1 microsecond of bias. Only upon the
situation of tracking or navigating it will output.

6.3 Recommendation reflow profile
1. We strongly recommend that this module should be designed to mount on
top side of motherboard with main chip together which process the final
reflow.
2. he maximum frequency of this module to pass reflow process should be
no more than twice, including repair operation, otherwise it may cause side
effect to the performance.
3. Below is the recommend reflow profile referred to Main chip M 3318.
