CA2RXU LoRa APRS Tracker on GitHub
Build a LoRa APRS Tracker with message, weather, and Winlink capabilities
Description
Demonstrates a LoRa APRS Tracker project featuring a comprehensive menu system for message management, weather requests, and monitoring nearby trackers. The device supports adjustable display eco mode and screen brightness, optimizing power consumption by dynamically changing processor speed from 240MHz to 80MHz. GPS beacons are encoded for efficient RF transmission, and an OLED screen displays altitude, speed, course, BME280 weather data, or new message counts, along with recently heard stations.
Bluetooth connectivity enables operation as a TNC with Android (APRSdroid) or iPhone (APRS.fi app), providing LED and sound notifications for transmissions and received messages. The integrated BME280 module facilitates weather data display and transmission, with Winlink mail support via APRSLink. The tracker can switch between three major LoRa APRS frequencies worldwide, offering versatile global operation.
