I have 2 LILYGO ESP32 LoRa OLED T3_V1.6.1 boards for general ESP32 experimenting.
They have the pin identifiers on the silkscreen on the opposite side of the board from where the OLED is mounted.
This means I wouldn’t be able to see the pin #’s if I solder the headers on the board, so the display is visible.
I was wondering what your advice would be — I noticed you did not use headers on the board in your course entitled:
