With the BrightSign USB Expansion Module, you can expand the interactive and audio potential of any display. The bi-directional GPIOs allow for the connection of up to 18 buttons or LEDs in a combination of your choosing (9 buttons and 9 LEDs, for example). This feature instantly makes any display more engaging. The digital and analog outputs support up to 3 simultaneous streams, enabling an immersive acoustic experience with flexible options. For example, you can link buttons (via the GPIOs) to the audio outputs, allowing users to listen to different audio sources on up to 3 speakers or headphones by pressing specified buttons. In addition, the optical SPDIF output provides even greater support for the A/V receivers.
