TL;DR
[Yeckel] has developed a simple D-STAR (Digital Smart Technologies for Amateur Radio) transceiver using affordable hardware, specifically the LilyGO TTGO T-Beam. This ESP32-based development board incorporates an SX1278 radio module and a GPS receiver, and it features a web interface for easy configuration. The project, called D-StarBeacon, allows for low-speed data transmission, making it possible to send text messages, GPS coordinates, and even images without needing a full-fledged radio setup.
