Note:
(1) GroundPlanes:
This pin2shouldbeconnecttoground.
(2) SerialInterface:
(Ⅰ)TheTXApin is recommended to connecttoserialresistance(220Ω)
and pull up(10KΩ). Itcanincreasethestabilityofserialdata.(Default
NMEA)
(Ⅱ)TheRXApin isrecommendedto connectto serialresistance(220Ω)
and pull up(10KΩ). Itcanincreasethestabilityofserialdata.(Default
NMEA)
(3) BackupBattery:
Whenmoduleis working,mustto supply VCCpin(Pin1)and VBATT
pin(Pin6)power atthesametime.
It srecommended toconnectabackup batteryto VBATTpin.
Inorderto enablethewarmstartand hotstartfeaturesoftheGPS receiver.
Ifyouusebackupbattery,should beadd abypassingcapacitor(10uF)at
VBATTpin.Itcanreducenoiseandincreasethestability.
