More than a year ago I started to work on my own LoRa based LRS system. And I did it. Not fully, did not implement telemetry of over-the-air configuration, but it worked pretty nicely and I did a couple of above 1km flights with it. In the end, I've abandoned the project since my FrSky was offering the same and more with smaller hardware, but the idea stayed. Lately, I started putting together something new... The LoRa based locator beacon for, you know, locating stuff. Car, husband, wife, lost drone, you name it.

This project utilizes Arduino, ESP32 and GPS to do exactly what the name says: make a long-range beacon based on LoRa and SX1278 chipsets from Semtech.

QmuBeacon! Right. Qmu stands for QuadMeUp ( https://quadmeup.com ) and Beacon stands for a beacon since it will be a UAV recovery beacon with a handy locator. LoRa modulation should give it a decent range with low output power.
My main problem will be, as usual, small hardware. The locator can be big, no problem, but I wonder how small I can go with DIY, no custom PCB approach...
