Note: The chip of GOKU GM10 V3 GPS is M1005. Only BF4.3x version firmware can use Ublox protocol. BF4.2x and earlier firmware can only use NMEA protocol But there is no difference in performance between the two protocols GOKU GM10 V3 GPS series is here! Using the latest M10050 GNSS chip. Compared with the previous generation GM8 V2, the positioning is more accurate, and the speed of star search is faster Description Brand: FLYWOO Model: GM10 MINI V3 GPS Dimension :18mm*18mm*4.8mm Weight : 4.7g Connector : 1.00mm spacing between the 4pins patch seat Features: GPS Module,Three Module 1.0mm spacing between the 4pins patch seat Specification Electrical Characteristics Chipset : M10050(Tenth Generation Chip) Receiving Format : GPS,GLONASS,Galileo,BeiDou,QZSS and SBAS Default Protocol : GPS,Galileo,BeiDou Frequency : GPS L1,GLONASS L1,BeiDou B1,SBAS L1,Galileo E1 Channels : 72 Searching Channel Sensitivity Tracking : -162dBm Reacquisition : -160dBm Data and Update Rate Support Rate : 4800bps to 921600bps,Default 115200bps Data Level : TTL or RS-232,Default TTL level Data Protocol : BF4.3.X(UBLOX)/BF4.2.X(NMEA) Output frequency : 1Hz-10Hz,Default 10Hz Operational Limits Altitude : 50,000m Max Velocity : 500m/s Max Acceleration : Less than 4g Power consumption VCC : DC Voltage :5V Operating temp : -40 °C ~ +85°C Storage Temp : -40°C ~ +105°C Indicator : PPS LED:yellow .PPS LED not bright when GPS not fixed,flashing when fixed The Module’s Pins: GND TX RX 5V Includes 1x GM10 MINI V3 GPS 1x 100mm Cable 1x Copper Foil
