Pedometer/Speedometer/Drone Delincomm Dm1616 Compact Mediatek Mt3339 Chip GPS Smart Antenna Module

General Description      Delin Comm DM1616 is a complete GPS engine module that features super sensitivity, ultra low power and small form factor.it with superior and performance even in urban can-yon and dense foliage environment.      This module supports hybrid ephemeris prediction to achieve faster cold start. One is self-generated ephemeris prediction (called EASY) that is no need of both network assistance and host CPU's intervention.This is valid for up to 3 days and updates automatically from time to time when GPS module is powered on and satellites are available. The other is server-generated ephemeris prediction (called EPO) that gets from an internet server. This is valid for up to 14 days. Both ephemeris predictions are stored in the on-board flash memory and perform a cold start time less than 15 seconds.FeaturesBuild on high performance, low-power  MediaTek MT3339 chip setUltra high Track sensitivity: -165dBmExtremely fast TTFF at low signal levelBuilt in high gain LNALow power consumption: Max 28mA@3.3VNMEA-0183 compliant protocol or custom   protocolOperating voltage: 2.8V to 4.3VOperating temperature range:-40to85ºCPatch Antenna Size: 15x15x4mmModule Size: 16.1x16.1x6.65mmCommunication type: UART/TTLRoHS compliant (Lead-free)IATF16949 quality control  ParameterSpecificationPower SupplySupply voltage:  2.8V~4.3V  Typical: 3.3VPower ConsumptionAcquisition:  28mA @VCC=VBAT=3.3VTracking:  20mA @VCC=VBAT=3.3VStandby:  1.0mA @VCC=VBAT=3.3VBackup:  15uA @VBAT=3.3VReceiver TypeCode 66 search channels, GPS&QZSS L1 1575.42MHz C/A22 simultan ous tracking channelsSensitivityTracking:   -165dBmRe-acquisition:   -156dBmAcquisition:   -148dBm TTFF (EASY enabled)Cold start:   15s  typ @-130dBmWarm start:   5s  typ @-130dBmHot start :   1s  typ @-130dBm  TTFF (EASY disabled)Cold start(Autonomous):   35s  typ @-130dBmWarm start (Autonomous):   30s  typ @-130dBmHot start (Autonomous):   1s  typ @-130dBm Horizontal PositionAccuracy (Autonomous)
