Heltec wireless tracker
Position-aware mesh communication in a pocket-friendly package with integrated GPS.
Important: 868 MHz for Europe
Always buy the 868 MHz version for use in Europe. The 915 MHz version (US) is not allowed in Europe.
Understanding the Heltec wireless tracker
The Heltec Wireless Tracker exists specifically for location-sharing scenarios. Integrated GPS hardware and an ESP32-S3 brain create a self-contained tracking solution.
The compact OLED panel (0.96 inches) shows your coordinates, network status, and incoming messages. Small enough to clip onto a rucksack or slip into a jacket pocket.
Through the SX1262 LoRa transceiver, your whereabouts reach others in the mesh even where Three, EE, and O2 show no Signal bars whatsoever.
