WAV32 is our new tiny stand alone board with 3W mono amplifier. 2 NO triggers or a sensitive touch connector to launch wav files. A potentiometer ables user to control volume power. This little device uses microSD card, 2 buttons to set up running parameters, and it can be powered with batteries or via a 5-6VDC adapter. WAV32 is particularly convenient to add audio sounds to any object or artifact (urban and public areas, paintings/posters, information speaking panels, security, vision impairment and disabled persons, ...).
