That is _almost_ correct.

Actual versions show ‘TTGO LoRa32-OLED V1’.

For clarity I have (just) added an overview:

See **Arduino Board Definitions** in [Big ESP32 + SX127x topic part 3](https://www.thethingsnetwork.org/forum/t/18436)

It is important to specify the correct full name of the board as specified in the left column in above overview because there are essential differences between the boards, especially with the TTGO boards.  
Many of those differences are not taken care of in the IDE because many version-specific board definitions are missing and the _names_ used in the Arduino IDE do not always (exactly) match the product name which can be very confusing. Both can lead to things not working (as expected).
