We are using HelTec Automation Wirelsess Sticks ESP32 Dev-Boards. Their GitHub repo can be found here: https://github.com/HelTecAutomation/Heltec_ESP32
If you are using _Arduino IDE_ (just to try them out) you can add their Repo to the library managers URLs: https://github.com/HelTecAutomation/Heltec_ESP32/blob/master/library.json and/or find them in the IDE (Sketch -> Include Library -> Manage Libraries... Search for "heltec esp32").
