I've build a GPS tracker with ESP32 soldering, assembly & first test makermoekoe

This device is the first prototype of a localization system for my old camper van. It is based on an Ai-Thinker A7 GPS & GSM module which is communicating over serial with an ESP32 Pico D4. For input & output I have added two buttons and an 0.96" OLED display, but the main idea is that the device can be control by a smartphone App. As you can see in the end of the video I'm using the Blynk 2.0 App which works great for several IoT projects, even for those which are communicating over mobile radio.
