   The Technovision® TM21 was primarily designed for kiosk applications, allowing for playback of MP3 (MPEG1-LAYER 3) audio through various pushbuttons, motion sensors or any device capable of a dry contact closure. Now, with the addition of the TM21SB board, you can now get RESTART, PREV, NEXT, VOL- and VOL+ functions using a MEM5 membrane keypad.
