5. User Interface
M-9329 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-9329 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-9329 is capable of supporting following NMEA formats:
NMEA RECORD
GGA
GLL
GSA
GSV

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. 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.
