5. User Interface

M-93 provides 2-wire digital UART port for communication of GPS position

data using NMEA protocol or MTK extension protocol. UART port is capable of
4800 to 115200 baud rate.

5.1 NMEA Protocol
M-93 is default to support standard NMEA-0183 protocol. In addition, a series

of MTK extensions (PMTK messages) have been developed that can be used
to provide extended capabilities common to many applications.

5.2 NMEA Protocol format
M-93 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 Speed

6.4 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. The 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 MTK chipSet.
