M5Stack Mini GPS/BDS Unit (AT6558)
This Mini GPS is an M5Stack unit that integrates an AT6558 navigation chip and a MAX2659 amplification chip which is used for amplifying the antenna signal.
The AT6558 is a high performance chip that supports many types of satellite navigation systems, 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.
You can plug it into port C on M5core via GROVE cable, which is a standard UART interface.
UART settings:
- Baudrate: (default: 9600bps)
- Start bits: (1 bit)
- Stop bits: (1 bit)
- Parity: (no)
Features
- Support single system positioning of BDS/GPS/GLONASS satellite navigation systems, or multi-system joint positioning in any combination
- Support D-GNSS differential positioning
- Two Lego-compatible holes
