GPS Engine BoardM-93295. User InterfaceM-9329 provides 2-wire digital UART port for communication of GPS position datausing NMEA protocol or MTK extension protocol. UART port is capable of 4800 to115200 baud rate.5.1 NMEA ProtocolM-9329 is default to support standard NMEA-0183 protocol. In addition, a series ofMTK extensions (PMTK messages) have been developed that can be used to provideextended capabilities common to many applications.5.2 NMEA Protocol formatM-9329 is capable of supporting following NMEA formats:NMEA RECORDDescriptionGGAGPS fix dataGLLGeographicGSAGNSS DOP and active satelliteGSVGNSS Satellites in viewRMCRecommended minimum specific GNSS dataVTGCourse Over Ground and Ground SpeedZDATime & Data- 10 -

GPS Engine BoardM-93296.3 Recommendation reflow profile We strongly recommend that this module should be designed to mount on topside of motherboard with main chip together which process the final reflow. The maximum frequency of this module to pass reflow process should be nomore than twice, including repair operation, otherwise it may cause side effect tothe performance. Below is the recommend reflow profile referred to Main MTK chipSet.- 15 -
