Which Library to use

Hi
I’m newbie in LoRa and LoRaWan projects.
I have many development boards like

  • CubeCell – AB01 Dev-Board (V2)
  • CubeCell 1/2AA
  • WiFi LoRa 32(V3)]
  • Wireless Tracker

I prefer to uso platformio as develpment platform.
I can’t understand which dependency library to include and where can I find examples including LoRa and LoRaWan.
I found:

  • HelTecAutomation/CubeCell-Arduino (does not include examples)
  • HelTecAutomation/ESP32_LoRaWAN (include examples but I think is deprecated)
  • HelTecAutomation/Heltec_ESP32 (I don’t understand the diff with the previous one)
  • Heltec-Aaron-Lee/WiFi_Kit_series (does not include examples)
  • eiannone/Heltec_Esp32_LoRaWan (I can’t understand the relationship with the other libraries)

Please I need a minimum guide about what to use in each case and where can I find examples.

Thanks

Specifically for LoRa and LoRaWAN: RadioLib is the one library that would be able to run on all of those, without too much trouble.
It does not require all the Heltec software BS.
