The SQ can output any combination of the following NMEA strings every second:
(details start on page 143 of the SQ datasheet)
GGA-GPS fix data
GLL- Geographic position
GSA- GPS DOP and active satellites
GSV- GPS satellites in view
RMC- Recommended minimum specific data
VTG- Track made good and ground speed
ZDA- Date and time
In order to simplify the use of the SQ, I developed a small interface PCB. The board connects the SQ through a .050 pitch connector to a more usable header with .1 inch centers. The board also provides backup power for the SQ?s battery-backed ram and provides 3.3volt regulation for the GPS receiver.
