This is the M5Unit version of GPS, integrates a Zhongke Weibeidou navigation chip AT6558 and a
amplification chip MAX2659 used for amplifying antenna signal.
AT6558 is highly performance, supports many types of satellite navigation system,able to receive satellite
signals on 56 channels GNSS signal from 6 satellite navigation system, joint location, navigation, timing
and more. The module is able to obtain accurate global location information. quick and accurate
positioning for anywhere in the city, in the canyon, under the overhead, and inside the car.
The module can be widely used in vehicle monitoring, bus reporting, car navigation, onboard navigation,
notebook navigation and other products.
You can plug it into port C on M5core via GROVE cable, which is a standard UART interface.
