The Gravity: GNSS GPS BeiDou Positioning Module with RTC Function has the ability to turn off the GNSS when not in use, leaving only the RTC module to maintain time, resulting in lower power consumption. Features Integrated GNSS and RTC Functionality Automatic Satellite Time Calibration RTC Chip Calibration Power Efficiency Satellite Signal Loss Mitigation Specification Operating Voltage: 3.3~5V DC Output Signal: I2C/UART GNSS IC: L76K GNSS Accuracy: 2.0m CEP First positioning time: 30s (Cold start), 2s (Hot Start) Operation current: GNSS enable: 46mA GNSS chip off ＜1mA Antenna Interface: IPEX 1 Antenna Frequency: 1561~1575.42MHz±3MHz RTC IC: SD3031 Time range: Year 2000~2099 Time Accuracy: ±3.8ppm @25℃ PCB Size: 32mm*42mm WIKI: https://wiki.dfrobot.com/_SKU_DFR1103_Gravity_GNSS_Position_And_Timing_Module Shipping List Gravity: GNSS Positioning & Timing module x1 GPS / BeiDou Active Ceramic Antenna (IPEX1 Connector) x1 Gravity 4P sensor cable x1 10 P connector x1
