• MG-903 module makes use of multi-constellation GNSS chip powered through M9140 MG-903 helps concurrent reception of 4 GNSS (GPS, GLONASS, Galileo, and BeiDou) The high number of seen satellites allows the receiver to select the best signals This maximizes the position availability, specifically beneath not easy conditions similar to in deep city canyons u-blox Super-S (Super-Signal) know-how gives great RF sensitivity and may improve the dynamic position accuracy in non-line-of-sight eventualities The high-gain 18 x 18 x 4 mm antenna from CIROCOMM gives the best balance between functionality and small length The omnidirectional antenna radiation sample will increase flexibility for device installation GNSS u-blox M9140 (GPS, GLONASS, Galileo and BeiDou) Magnetic Compass IIST8310 Patch antenna 18*18*4mm Input voltage range: 4~6V (5V pad/pin) Power consumption: 50mA UART baudrate: 115200 default Operating Temperatures: -20~80 °C UART(TX, RX) interface for M9140 I2C(SDA, SCL) interface for Compass IST8310 SH-1 6P connector ,1 pitch GNSS PPS LED, Blue (Solid ON after powering on, blinking(1Hz) when GNSS get three-D fix) Protocol suppoort: UBX + NMEA (DEFAULT)NMEA 1Hz@GPS+GAL+BDS+GLONASS 20mm*20mm*8mm 7g
