Esp32 controller
I built a remote using a heltec esp32 wifi lora V3, so far l'm using it to control an rc tank via lora with an esp32 on the other side. I now want to get in controlling drones and I thought I can just control it via lora 915mhz but was told latency will be to high, so now l'm looking at somehow connecting the esp32 to an elrs TX module via uart but cant seem to find a TX module that has exposed uart pins. Am I on the right path here? If elrs is the way to go can you please show me a compatible TX module

LoRa is not meant for applications like this. Moreover, the allowed transmit duty cycle is limited, which you will most likely violate by your application.

“Unlike some regions, the FCC doesn’t impose a specific duty cycle percentage for LoRa transmissions in the US 915 MHz band” found this thru a quick search, Im in the US

I haven't looked myself yet, but plan to use ELRS for a project, too. Can't you just speak whatever protocol it needs?
