This a module that can be bought from China for less than £20, The board looks like it is made by a company called Heltec. however there site is in Chinese, so I can’t get specifications easily from them 🙁

The WIFI LoRa 32 board from heltec comes pre flashed with some firmware that runs it through a short demo. where it tries to send out LoRa packages.

Mine came without an external LoRa 868 MHz antenna, so I assume that the transmission is not leaving the Male U.FL connector on the PCB.

1. Run the following in a terminal:

   mkdir -p ~/Documents/Arduino/hardware/espressif
   cd ~/Documents/Arduino/hardware/espressif
   git clone https://github.com/espressif/arduino-esp32.git esp32
   cd esp32
   git submodule update --init --recursive
   cd tools
   python get.py

2. Add the following libraries to your libraries folder to enable the OLED and LoRa – OLED and LoRa Libraries
3. Restart your Arduino IDE
4. Profit.
