I am a sooo new to even try to solder and connect this stuff… But I have managed to program my ESP32 and found it/logged in via the browser…
However… when connecting - I have different markings than all other guides… I have no D2 or D16. But lots of G:s… And I have tried G2 with no effect… G16 gives the first LED a green light - but cannot change or do anything else. I dare try no more and cannot find any other thread that asks about hits.
The pins are GPIO pins. Manufactures can print anything they want on the boards you need to reference a pinout diagram for your board and cross reference it to what GPIO it is. Here is a pic for your board. Most times on Esp32 boards the #'s they have on them are the correct GPIO #. Not always though.
For your board:
‘G2’ is GPIO 2
‘G16’ is GPIO 16
Whatever you choose to use you also need to set in your LED Preferences page.
