Jamboard is a product for G Suite customers that features a 55-inch, digital, collaborative whiteboard that works in the cloud. You can create notes, text, and images on the board. And, whatever you put on the board can be shared with the rest of your team. The board comes with a passive stylus and an eraser (no batteries needed). The board can be wall–mounted or mounted on a moveable stand. For details, see Use Jamboard. For information about purchasing a board to use with the Jamboard service, go to the Jamboard site for G Suite customers.

Mobile apps, and web viewer

With the Jamboard app, you can use your phone or tablet to connect to a session or jam from anywhere. A web viewer allows you to view jams from any device with a web browser.
