HELTEC Wireless Tracker ESP32S3 SX1262 GPS Meshtastic LoRaWAN 915Mhz
The HELTEC Wireless Tracker is a compact, high‑performance IoT board built on the ESP32‑S3FN8 microcontroller, engineered for low‑power, long‑range communication and precise satellite positioning.
Equipped with the SX1262 LoRa transceiver and the UC6580 GNSS chipset, it supports multi‑constellation navigation systems including GPS, GLONASS, BeiDou (BDS), Galileo, NAVIC, and QZSS. With dual‑frequency (L1 + L5/L2) positioning, it delivers fast, stable, and highly accurate location data, even in dense urban areas with weak signals.
Connectivity is built‑in: Wi‑Fi, Bluetooth, and LoRa make it a versatile choice for Meshtastic mesh networks, GPS node development, and IoT applications such as asset tracking, bike navigation, pet monitoring, and child safety.
A 0.96‑inch OLED display provides real‑time system feedback, while the USB Type‑C interface ensures fast firmware flashing, reliable data transfer, and efficient power management. The integrated lithium battery charging circuit allows for portable use without external modules.
Designed for developers, the board is fully compatible with the Arduino IDE, making it beginner‑friendly yet powerful enough for advanced projects. Whether you’re building smart mobility solutions or deploying remote sensing nodes, the HELTEC Wireless Tracker offers the flexibility, accuracy, and reliability needed for modern IoT development.

Onboard LCD Display
GNSS data is displayed as ‘0,0,0’ ?
- Confirm your hardware version, V1.1 has changed the power control pin of the GNSS chip (GPIO 3 is set to HIGH on). Please carefully review the schematic or refer to the corresponding hardware version’s example program.
- GNSS requires open outdoor environments or try with an external antenna.
How LoRa Enhances Home Automation
LoRa technology provides long‑range, ultra‑low‑power wireless communication, making it an excellent choice for home automation projects where Wi‑Fi coverage is weak or unreliable.
For example, imagine monitoring soil moisture in a garden just beyond your home’s Wi‑Fi range. A sensor node built with an ESP32 microcontroller and a moisture sensor can collect data and send updates once or twice a day via LoRa. A second ESP32 device within Wi‑Fi range receives the data and hosts a simple web server, allowing you to view real‑time soil conditions from your phone or computer.
This approach highlights how LoRa‑enabled ESP32 boards can form wireless sensor networks for environmental monitoring, garden automation, or remote asset tracking—all without depending on continuous Wi‑Fi connectivity. With its extended range and minimal power draw, LoRa is a scalable, practical solution for both indoor and outdoor smart home applications.
Meshtastic Firmware & GNSS Support
Earlier versions of Meshtastic firmware had issues with V1.1 GNSS operation, but this has been resolved. The latest firmware automatically detects the device version and manages GNSS functionality seamlessly, ensuring reliable performance without manual configuration.
