Sending LoRa messages long distances without a radio
🕑 Added 2024-03-24 05:44:48 +0000 UTCThis video has been a LONG TIME COMING. And, it's finally here! You can send LoRa signals now with a variety of processors, without any extra hardware, just your normal micro-controller and just careeefullyyy control the GPIOs to modulate and transmit LoRa.
The insane part isn't that this works. It's how far it works! Not just reasonable or far distances but truly ludicrous distances.
This version of the video is a release candidate and may not be the final one and as always, please do not share until the public version goes live. This early sneak peek is for patrons.

It would absolutely be better, and maybe for another video I might add some extra external parts, but this was all a question of can I make it work with no external components.

That's nice didn't know its possible to mix signals without external mixer circuit. But a band-pass filter on the rf output is highly recommended to dampen all the harmonics. but again a really interesting project thanks a lot!
