GPS is build with NEO-M8N, u-blox M8 concurrent GNSS modules and come with an active Antenna.
The NEO-M8 series provides high sensitivity and minimal acquisition times while maintaining low system power.
The NEO-M8N integrates a 72-channelu-bloxM8 GNSS engine that supports multiple GNSS systems ( Beidou, Galileo, GLONASS, GPS / QZSS ) and able to receive 3 GNSS systems simultaneously.
he series communicate protocol between M5Core and GPS is UART, physically connected viaUART2 (GPIO16, GPIO17)
If you want to Change the uart baudrate,please check here (u-center-just-for-Windows)
Notice: GPS signal can only be found outdoors
