Out of various cheap modules available in market for LORA protocol, cheapest option available is TTGO which comes with an on board SMA antenna port and OLED. LORA has its own capabilities however we can still use this module as BLE or ESP module.

Components needed:

First things first, you need to setup the Arduino with required libraries and Boards. For ESP and LORA setup from this website (RNT tutorials) could be handy.

Select the correct COM port and Board, as shown on the website in step 1

Additionally the tutorial is really helpful.

Download and open the attached code (.ino file) onto your machine.

2) And upload.................

You can now customize this display or add an case for this module and place it at any place you like

IMPORTANT: standalone module may require battery device like powerbank or source. (keep something like that handy)
