5. User Interface
M-89 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 Protocol
M-89 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
M-89 is capable of supporting following NMEA formats:

6.3 Recommendation reflow profile
THE PRO NAME IN GPS
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 chip MT3318.
