This project demonstrates how to build a real-time GPS tracker using the Heltec WiFi LoRa 32 V4 and the REYAX RYS352A GNSS module. The tracker hosts its own web interface, allowing any device on the same Wi-Fi network to monitor live location and travel history directly from a browser. The project processes NMEA data locally, displays live coordinates on the onboard OLED, and visualizes the current location and travelled path on OpenStreetMap without relying on cloud services.
