Ide 2 Portable - Arduino

Instructors can prepare a single portable installation containing all the necessary libraries, board definitions, and example sketches for a workshop. This folder can then be copied to every student's machine, ensuring an identical starting environment for all participants.

#!/bin/bash SCRIPT_DIR="$(dirname "$(readlink -f "$0")")" export ARDUINO_DATA_DIR="$SCRIPT_DIR/arduino-data" export ARDUINO_SKETCHBOOK_DIR="$SCRIPT_DIR/arduino-sketchbook" echo "Starting Arduino IDE 2.0 in Portable Mode..." "$SCRIPT_DIR/arduino-ide" --user-data-dir "$ARDUINO_DATA_DIR" & Use code with caution.

Because Arduino IDE 2.x uses an underlying CLI tool ( arduino-cli ) to manage compilation and boards, we need to instruct the IDE to look at our new local folders instead of default system paths.

When moving to a different computer:

This approach ensures that board packages, libraries, and even the IDE's internal state are all stored on your USB drive, creating a fully self-contained environment. arduino ide 2 portable

By editing this configuration file, you can redirect where the IDE stores various types of data:

When you plug your drive into a new computer and run the IDE, the system will generate a new arduino-cli.yaml in the host computer's user folder. You will need to re-edit that file to again point the data: and user: paths to your USB drive.

The Arduino developers have noted that IDE 2.x is a major rewrite based on the Theia framework and Electron . Adding a native portable mode is currently a on their GitHub roadmap because most users now use personal laptops rather than shared machines, reducing the immediate demand for the feature.

export HOME="$NEW_HOME"

Change the to point directly to the sketchbook folder you created on your USB drive (e.g., D:\ArduinoIDE_Portable\sketchbook ). Close the IDE.

Even with this workaround, some limitations persist:

Go to inside the IDE. You will see that the Sketchbook location is pointing directly to your USB or local folder instead of your main Windows Documents folder.

The cleanest way to do this across different machines is by creating a launch script that sets local environment variables before starting the IDE. For Windows users (Batch Script Method): Because Arduino IDE 2

data (This will store your board manager files and index preferences)

To set up a portable version, you must use the "ZIP file" (Windows) or "AppImage" (Linux) versions rather than the standard installer. Is there a portable version? - IDE 2.x - Arduino Forum

: Share an identical development environment with students or team members by copying a single folder.

By placing the portable folder in a cloud-sync directory (like Dropbox or OneDrive), you can keep your entire development environment identical across multiple workstations. Limitations and Considerations You will need to re-edit that file to

# Original data: C:\Users\YourUserName\AppData\Local\Arduino15

A portable setup isolates your development environment into a single folder.
