Scratch Link is a downloadable program that enables Scratch 3.0 to connect to and control devices in the physical world. It was developed by the Scratch Team for use with such devices as EV3. Scratch projects can access these devices using extensions. Like Scratch, Scratch Link is free software (provided under the BSD 3 clause license.) Scratch Link requires macOS 10.10 (Yosemite) or later or Windows 10 version 1709 (Fall Creators Update) or later.
It can be downloaded directly from the Scratch Website for Mac or Windows, or it can be installed from the Microsoft Store (Windows) or the App Store (macOS).
Downloading Scratch Link
Scratch Link can be downloaded from the Scratch Website, Mac App Store, and Microsoft Store.
The system requirements of Scratch Link are as follows:
Windows
- Windows 10 Fall Creators Update (1709) or newer
- Architecture x86, x64, ARM, ARM64
- At least 2.5MB of free storage space
macOS
- OS X 10.10 or newer
- 64-bit processor
- At least 5MB of free storage space
It is also compatible with ChromeOS and Android via the Scratch App, but not (GNU/)Linux.
How It Works
 Note: | The device with Scratch Link needs a Bluetooth receiver in order to work. |
Scratch Link connects to the device via Bluetooth. This means that the device needs to have Bluetooth enabled to connect. When a project is running, Scratch Link uses Bluetooth to communicate between the device and Scratch.[1]
