Dl-2525n-Gcmr GPS Smart Antenna Module, 9600BPS, 25X25mm

The DelinDL-2525N-GCMRis a completeGPS engine module that features supersensitivity, ultra low power and small form factor. The GPS signal is applied to the antennainput of module, and a complete serial data message with position,velocity and time information is presented at theserial interface with NMEA protocol or custom protocol.Its -165dBm tracking sensitivity extendspositioning coverage into place like urban canyons and dense foliage environment where the GPS was not possible before. The small form factor and low power consumption make the module easy to integrate into portable device like PNDs, mobile phones, cameras and vehicle navigation systems.ApplicationsLBS (Location based Service)PND (Portable Navigation Device)Vehicle navigation systemMobile phoneFeaturesBuild on high performance, low-power MediaTek MT3337 chip setUltra high Track sensitivity: -165dBmExtremely fastTTFFat low signal levelBuilt in high gain LNALow power consumption: Max 28mA@3.3VNMEA-0183 compliant protocol or custom protocolOperating voltage: 3.0V to 5.0VOperating temperature range:-40to85ºCPatchAntennaSize:25x25x4mmModule Size: 25.5x25.5x8.8mmCommunication type: UART/TTLRoHS compliant (Lead-free)ParameterSpecificationPowerSupplySupply voltage: 2.8V~4.3V Typical: 3.3VPowerConsumptionAcquisition: 28mA @VCC=3.3VTracking: 25mA @VCC=3.3VStandby: 2.0mA @VCC=3.3VBackup: 15uA @VBAT=3.3VReceiver TypeCode 66 search channels, GPS&QZSS L1 1575.42MHz C/A22 simultan ous tracking channels
