While it's cool and all to use specifically designed hardware for transmitting data, what happens when you don't, and all you have is some time code and a little bit of I/O? This is a follow-up talk to a video released in March 2024 where LoRa packets were transmitted over a mile with just a microcontroller, wire, and a dream.
LoRa is a low-speed radio protocol used by commercial gateways, and networks like the Helium Network. Originally there were a few different ways to transmit radio signals with just a wire and a GPIO, see the creation of these signals in real time and get a feeling for some of the new ways found to generate radio signals... without a radio.
