I want to make a walkie talkie with Arduino. I want to do it cheaply. LoRa or which module can I use? I want a range of 3 4 5 km.
If you want it cheap, probably best to buy a ready made one.
But before assuming its even possible, then you need to appreciate that just saying you want 5km is no real information at all. Simple low cost stuff might well work 5km clear line of sight, say hilltop to hilltop, but might only get 50-100m in an urban area. So 5km in an urban area can be really difficult and expensive and maybe illegal too.
With a pair of Adafruit Feather Lora modules, you can send text messages out of the box, 10 km with clear line of sight. Cost about USD $70 for a pair, plus shipping.
Have fun!
5km... kidproof.
