ChristineNZ, whose clock projects you may have seen here before, decided to do something a bit different with her latest build. She created a GPS route tracking device that's powered by an ESP32 development board along with a NEO-7M-0-000 GPS module and a DS3231 RTC. The unit it capable of sensing the current position via GPS, saving it on a microSD card.

When the journey is over, route data can be transferred to a PC using a card reader, or more interestingly, the ESP32 module can also send it as an email to a Gmail account. The only trick here is that you’ll need to set up Gmail to receive “less secure” emails, as apparently the format that the ESP32 generates is seen a suspicious. This info can then be used with either Google Earth Pro or the Google GPS viewer application depending on which save format is selected.

ChristineNZ is able to choose from various data formats, email options, and to start and stop the route recording with a pushbutton, while a 0.96” OLED screen displays the current longitude and latitude or can show other details like altitude, current time, and number of satellites being used. Though the GPS unit can obtain the time, the RTC module is used to track local time.
