The VIA-GO3 is a compact wireless presentation device that lets users on iOS, Android, Chromebook, Windows and Mac connect to a main display without cables or a dongle, using AirPlay, Miracast or browser-based joining. It includes built-in Wi-Fi and LAN connectivity, 1024-bit encryption, and supports up to four people presenting to the same screen at once. Its small form factor (around 9x9cm) allows it to be mounted discreetly behind a display or projector, making it suited to meeting rooms, classrooms and similar shared-screen environments.
