Recommend LilyGO/TTGO do a pull request on https://github.com/espressif/arduino-esp32 to merge an entry LORA-ESP32-OLED to boards.txt and add a folder to variants so these boards can be used in Arduino. They are similar to the Heltec boards but LED_BUILTIN = pin 2 instead of pin 25. Please see my examples at https://github.com/CaptIgmu/Arduino/tree/master/esp32/TTGO_LoRa32_OLED. Thank you!
