Talk-E is a walkie-talkie powered by LoRa and an ESP32-S3, operating on the 433 MHz band. And it mostly works.
- What : Two identical devices, one button to talk, and that's it.
- Why : We didn't have much time, so we wanted something original, interactive, and fun to demo. The kind of project you understand immediately just by holding it in your hands.
- Context : Radiocommunication student project, two-person team.
The documentation is quite detailed, so each part has its own page instead of having it all here.
