In order to develop ESP32-S3 with Arduino IDE, you need to add an additional source to the Arduino IDE board manager and then install ESP32.We need to add the ESP32 development board additional URL first.Open the Preferences under the File menu.
Copy and paste the following link into the Additional Development Board Management website:
Install the ESP32 development board, select the Tools menu -> Board Manager...
Search for esp32 in the search bar, you can see the esp32 library, select the latest version, click install, and wait for the installation to complete.
Select the corresponding development board ESP32-S3 Dev Module, select the corresponding port for ESP32-S3
Finally, we find the official example code and click to upload.
Common questions: Solution for upload failure: Remove all the modules connected to the development board.
