        Hi.
        When you say VDD3V3, you mean:
        a) that on the FT232-AZ USB auf TTL adapter:

        or
        b) that on the LilyGO ESP32 module:

          @m4biz The USB adapter is powered by 5v, obviously, and the ESP32 needs 3.3v.
          Arduinos such as Arduino Uno and other Atmel chipped boards use 5v, so this option needs to be set to 3.3v for ESP32!
          I did not know your TTL had this option, so set it to output 3.3v.

            Shure, the adapter is set on 3.3 V.
            Anyway, in the circuit you have uploaded I see VDD3V3

            I don't know where must I take this voltage from the ESP32 module or from the FT232 adapter ?

              @m4biz VDD and VCC are typical power supply markings in electronics.
              The number VDD3V3 means 3.3v, which is a standard for all ESP32s and almost all new sensors.
              Your board needs to be powered somehow, so set the TTL to 3.3v. The TTL will power the board.
              After uploading your sketch you will need the TTL connected to power it, or you will have to get a standalone 3.3v power supply.

                Nothing to do.
                I've tried all but don't works.

                  Thank you for responding, I'm still willing to help.
                  It is ironic that these cheap "AliExpress" boards, like LilyGO and Lolin save you 3$ by not getting the USB model but require much more advanced experience to handle. I see this ALL THE TIME.
                  Even new guys with a ESP32 S3 latest board WITH USB will still be difficult to get a sketch downloaded and run.
                  I have been with Arduino for 10 years and these new boards are very difficult, not Plug'n'Play!
                  I could draw out a complete circuit for you, I f you like.
                  Also...does the Arduino IDE even recognize the port?

                    (you need to cross over TX to RX so that the TTl TX is the LilyGO RX !)

                      Wonderful!!!
                      Works.
                      Thanks for you time.

                        @m4biz Fantastic news!

                        You can also put a small
                        delay(500);
                        In the loop to keep it from locking up and becoming very hard to upload another sketch!

                        But: GREAT JOB !
