Summary
Wireless Tracker is a development kit based on ESP32-S3FN8. It integrates both SX1262 and UC6580 to provide fast GNSS solution for IoT. It can track any object and then upload that data wirelessly by Wi-Fi, Bluetooth, LoRa, and has been widely used in Meshtastick.
Wireless Tracker supports L1 + L5/L2, and supports GPS, GLONASS, BDS, Galileo, NAVIC, QZSS multi-system joint positioning. It is perfectly compatible with Arduino, can be widely used in development such as bicycle sharing services, tracking pets or livestock, locating vehicles, tracking children, etc.
Main Features

FAQ
1. Check if the USB cable supports data transfer by verifying if the connected cell phone supports file transfer.
2. Connect the USB cable, press and hold the ‘USER’ key, then press the ‘RST’ key once. Finally, release the ‘USER’ key to initiate the code download.
Connect the serial port and check whether the node is activated. If the node is not activated, refer to this link to activate it: https://docs.heltec.org/general/how_to_use_license.html.
- 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.
Imagine that you want to measure the moisture in your field. Although, it is not far from your house, it probably doesn’t have Wi-Fi coverage. So, you can build a sensor node with an ESP32 and a moisture sensor, that sends the moisture readings once or twice a day to another ESP32 using LoRa.The later ESP32 has access to Wi-Fi, and it can run a web server that displays the moisture readings.This is just an example that illustrates how you can use the LoRa technology in your ESP32 projects.
Please refer to this document:
This issue had been well solved in the last update. The firmware will automatically recognize the device version and operation it.

Greg Hall –
The Wireless Tracker has the very good UC6580 GNSS ‘L1+L5/L1+L2 dual frequencies’ & positioning accuracy better than 1.5 m’.
Heltec is supporting maker community very well now.
Example Arduino code for using this device as ‘Bluetooth external GNSS service to phone’ will be very helpful for accurate field mapping, tracking, etc.
dicktonyboy (verified owner) –
Excellent low cost board. All ready for a beginner to experiment with.
Has all of the basic features USBC, OLED, Good processor, GNS, Power management etc which is why it is the most popular board for ‘Meshtastic’. It’s not the lowest power (consumed) board but performs well. All update/download are well supported from the online flashing facility – that is a breeze to use.
