 - `arduino.path` - Path to Arduino, you can use a custom version of Arduino by modifying this setting to include the full path. Example: `C:\\Program Files\\Arduino` for Windows, `/Applications` for Mac, `/home/<username>/Downloads/arduino-1.8.1` for Linux. (Requires a restart after change). The default value is automatically detected from your Arduino IDE installation path.

 - `arduino.disableTestingOpen` - Enable/disable automatic sending of a test message to the serial port for checking the open status. The default value is `false` (a test message will be sent).
 - `arduino.skipHeaderProvider` - Enable/disable the extension providing completion items for headers. This functionality is included in newer versions of the C++ extension. The default value is `false`.
 - `arduino.defaultBaudRate` - Default baud rate for the serial port monitor. The default value is 115200. Supported values are 300, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 74880, 115200, 230400 and 250000.
+- `arduino.defaultOutputPath` - Default output path for the compiler. By default, this option is not set.
 
 The following settings are as per sketch settings of the Arduino extension. You can find them in
 `.vscode/arduino.json` under the workspace.
