Heltec 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. We can set a low-power mode on Meshtastic to extend battery life.
