Module GPS

Description

The NEO-M8 series provides high sensitivity and minimal acquisition times while maintaining low system

The NEO-M8N integrates a 72-channel u-blox M8 GNSS engine that supports multiple GNSS systems (

Beidou, Galileo, GLONASS, GPS / QZSS ) and able to receive 3 GNSS systems simultaneously.

The series communicate protocol between M5Core and GPS is UART, physically connected via UART2

(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

UART protocol: baud rate (default is 9600bps), data bit (8 bits), start bit (1 bit), stop bit (1 bit), Parity (none)

M5Stack Docks M5Stack Fire has occupied GPIO16 / 17 to connect with the PSRAM by default, it's conflict TXD / RXD (GPIO16, GPIO17) of GPS module. Therefor the M5Stack Fire, you might have to cut the TXD and RXD from GPS module and wire fly to another set of UART pin Product Features Operating voltage: 2.7 ~ 3.

M5Stack Docks EasyLoader is a simple and fast program burner. Every product-related case program. It can be burned to the master through simple steps, and a series of function verification can be performed.(Currently EasyLoader is only available for Windows OS) 2.After downloading the software, double-click to run the application, connect the M5 device to the computer via the data cable, select the port parameters, and click "Burn" to start burning. 3.
