I'm looking to get 2 LORA modules that will be able to communicate with eachother, transcievers, so that they can both send and receive. I intend to connect them to an Arduino Uno or similar.
Any suggestions from users that have had good results from anything on Ali Express?
Suggestions from UK sources welcome too, but I would like to get something as cheap as possible, while still working.
I use modules from Heltec, more money, but now I have 2 self contained (except for a small battery pack) radios. Here is my Canadian Amazon LINK
, change the country as required. Make sure you get the frequency for your country.
don't recommend UNO which uses 5V logic most LoRa modules use 3.3V
I would recommend you go for modules with microcontroller and LoRa wireless on a single PCB - this saves problems with different logic levels, possible poor interconnections, etc
try web and ebay searches TTGO LoRa32 SX1276 OLED which have on board ESP32 microcontrollers - the ESP32 itself has onboard WiFi, Bluetooth Classic and BLE which give you more communications options
in the UK I tend to use 868MHz LoRa modules
do you require LoRa ? give details of your project, e.g. distance between stations, volume of traffic, etc
