By default, the Arduino IDE only supports official Arduino boards. You can easily add support for the ESP32 by using the Boards Manager.
- Go to the Preferences and look for the field "Additional Board Manager URLs".
- Paste this link in there:
Tip: If you want multiple custom boards: separate the URLs with commas
Next step it to actually install the required software.
- Head over to
Tools > Board > Board Manager....
- Search for "esp32"
- Select the board and click on "Install".
That's all! The Arduino IDE will take care of downloading the necessary toolchains & setting them up for your machine.
