This guide will show how to install the Arduino-ESP32 support. We recommend you install the support using your favorite IDE, but other options are available depending on your operating system. To install Arduino-ESP32 support, you can use one of the following options.

This is the way to install Arduino-ESP32 directly from the Arduino IDE. For overview of SoC’s support, take a look on Supported Soc’s table where you can find if the particular chip is under stable or development release. Starting with the Arduino IDE version 1.6.4, Arduino allows installation of third-party platform packages using Boards Manager. We have packages available for Windows, macOS, and Linux. You can find the latest Espressif-IDE release notes at here. Direct download links for various platforms are provided below.

On macOS, if you download the archive using a web browser, the strict security checks in recent macOS versions will prevent it from running and display a message that the program is damaged. This is not actually true, and the fix is simple: you just need to remove the com.apple.quarantine extended attribute. After unpacking the archive, if the application still shows the same warning, check and remove the attribute from the Espressif-IDE.app folder as well: © Copyright 2016 - 2024, Espressif Systems (Shanghai) Co., Ltd.
