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.
