GPS is an M5Stack Unit that integrates a AT6558 navigation chip and a MAX2659 amplification chip which is used for amplifying the antenna signal.
AT6558 is an 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.
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.
UART settings :
- Baudrate(default: 9600bps)
- Start bits(1 bit)
- Stop bits(1 bit)
- 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
- 1x GPS Unit
- 1x Grove Cable
- Vehicle positioning and navigation
- Smart law enforcement positioning

LEARN AND DOCUMENTS
works very easily with all the rest of the M5stack bits I have, and I was able to get it to work with a raspberry pi pico without much difficulty as well.
All tue items arrived in good time and work!
I am very happy with it, I am using it in my test tracker
Long awaited modules and sensores for some ideas.
Works really well. Fast acquisition.
