Features:
1、Passive buzzer without oscillating source inside, so if you use DC signal, you can't make it scream. It must be driven by a square wave of 2K~5K. 2、The sound frequency is controllable, and the effect of ''do re mi fa so la si do'' can be made. 3、In some special cases, a control port can be multiplexed with the LED. 4、Equipped with fixture nuts for convenient mounting. 5、The module is driven by 9012 transistor.Uses 3 pin control port.
