1. Description

1.1 Overview

Wireless Tracker is a development kit based on ESP32-S3FN8. It integrates both SX1262 and UC6580 to provide fast GNSS solution for IoT. Collaborate with the sample programs and development tools we provide, you can track any object and then upload that data wirelessly by Wi-Fi, Bluetooth, LoRa. Wireless Tracker supports L1 + L5 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. Wireless Tracker are available in two product variants:
