Apart from the five Microduino modules that have been mentioned above, I have also prepared a SD card, a battery, copper cylinders, screws, and weather station floor without sensors.
Because Core+ supports two-way serial ports. The material in wiki:
Click on me.)So I change the communication of GPS module into serial port 1: D2 and D3 here, and in this way the serial port 0 is freed up for easy of program debugging.
Module Assemblage
Put the SD card into the SD module at first, and put the GPS antenna into the IPEX socket of the GPS module.
Connect the wires of OLED.
Connect to the corresponding interface on the baseboard.
The USBTTL module can be taken away after downloading programs to Core+.
Stack modules, and assemble the baseboard and battery!
Electrifying and Using
Start up BM, and electrify!If there is no signal indoor, go out!
Waiting for a few minutes, when the GPS signal light twinkles, it means there is a signal. At this time, press D5, then it can start to create a new file and record the trajectory in the SD card.
Walk to try it.
Exporting to View
To stop recording, press D5 again, and the screen will prompt the name of the file that has been created.
Take away the SD card, connect it to the computer with a card reader, and you will see the file that has been created, whose name is picked in the form of year – month – day – number, in order to be managed easily.
Open the Google earth, and choose “Tool”-“GPS” the toolbar.
Setting is as shown in the picture. Click to import, and select the file created.
You will see the trajectory that you have walked!
Click on the trajectory points, you can see more detailed information such as speed, altitude, coordinates and so on.

Note:
1.To get the support for Core+, you need to download the Microduino hardware support package:
(Click here).
2.The Core+ and the official original SD library is not compatible, so please to download the SD library that has been modified by Microduino official.(For the sake of compatibility, if you use the complete library support package, you’d better empty all library files in IDE original Library.):
