  Parts

  To make this you will need an ESP32 board or an ESP8266 and you can also add a battery if you want.

  I used firebeetle LoRa board of 915MHz frequency. DFRobot offers 3 types of boards depending on the frequency that is legal in your area:

  1)  433MHz

  2)  868MHz

  3)  915MHz

  For the display, I used an OLED shield.

  I suggest using boards from DFRobot with this module as the pinout will be compatible and you will face no issues anywhere.
