@ptillisch and do you have any idea how I can get this LED to blink ?

I even tryed

but it didnt worked ....

which exact ESP32-S3 do you have?

the ESP32-S3-WROOM-1 is just a chip, there is no LED...

any reason why you are pinging @ptillisch specifically?

GPIO 38 is the RGB LED ...

if I run the following code it blinks the large white LED

/*
  Blink

  Turns an LED on for one second, then off for one second, repeatedly.

  Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO
  it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to
  the correct LED pin independent of which board is used.
  If you want to know what pin the on-board LED is connected to on your Arduino
  model, check the Technical Specs of your board at:

  This example code is in the public domain.

*/

// the setup function runs once when you press reset or power the board
void setup() {
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(LED_BUILTIN, OUTPUT);
  Serial.begin(115200);
}

// the loop function runs over and over again forever
void loop() {
  Serial.print('*');
  digitalWrite(LED_BUILTIN, HIGH);  // turn the LED on (HIGH is the voltage level)
  delay(1000);                      // wait for a second
  digitalWrite(LED_BUILTIN, LOW);   // turn the LED off by making the voltage LOW
  delay(1000);                      // wait for a second
}

make sure you connect the USB cable to the correct C-type (right hand in your picture in post 3)
after upload you have to press RST
