Description Grove for Scratch is a USB-powered expansion board for controlling Grove sensors and actuators with the visual programming environments Scratch and Stretch3. Its built-in WebSerial support lets compatible browsers communicate with the board directly, so no Arduino setup or Scratch Link installation is required. The wired USB connection supplies power and avoids Bluetooth pairing. Connect the board to a computer, open the supported browser-based environment, and build programs by arranging visual blocks. Note: Grove for Scratch does not come with a USB cable or Grove cable. Features Browser-ready WebSerial: Works in supported browsers without installing Scratch Link. USB powered: Operates from the connected computer without an external battery. No wireless pairing: The USB connection provides a straightforward plug-and-use workflow. Six Grove ports: Two analog, two digital, and two I2C ports support multiple Grove modules at the same time. Visual programming: Scratch block programming makes the board approachable for students and beginners.
