The GPS module is a M5Stack series stackable module with built-in GPS small module. The built-in GPS small module name is UBLOX NEO-M8N.
After stacking M5Core, you can program it with UiFlow, , and MicroPython. Global positioning information is available even when you are outdoors. After the module is powered on, it will always receive positioning information.
The M5Core programming routine, after stacking the GPS module and connecting the PC serial port, the screen and the PC's serial display terminal will print the information received by the GPS.
The GPS Module internally communicates with the M5Core via UART2 (GPIO16, GPIO17) by default. You can modify it by modifying the 0 ohm resistor jumper.
