Using the ESP32-S3-DevKitC-1 in the Arduino IDE

Step	Image
Make sure you have the Arduino IDE installed and open
In the menu, go to File > Preferences
- Set the language to English so it’s easier to find help online. - Enable Show verbose output during for compilation and upload. This gives you more information when something goes wrong.
Add the following URL to Additional Boards Manager URLs: https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_dev_index.json This ensures the Arduino IDE knows how to program the ESP32-S3.
Go to Tools > Board > Boards Manager, search for “ESP32”, and install the ESP32 libraries by Espressif.
Connect your board to your computer with a USB‑C cable and use the USB‑C port on the board labeled USB. See the image.
Open the Blink example: File > Examples > 01.Basics > Blink
Select the correct port and board in the top-left of the Arduino IDE. Choose “Select Other Board & Port”.
Select the correct port. This depends on your OS: Windows: Usually COM3 or COM4. macOS: Usually something like /dev/cu.SLAB_USBtoUART or /dev/cu.wchusbserial/. Linux: Usually /dev/ttyUSB0 or /dev/ttyUSB1.
Select the correct board. This is the ESP32S3 Dev Module.
Upload the example to your board by clicking the upload button (the right-pointing arrow) in the top-left of the Arduino IDE.
