Specification Brand : Yanmis BulletPoint : Made in United States BulletPoint1 : Module is driven with 9012 transistor. BulletPoint2 : External connection of 3.3V-5V voltage, can be directly connected to 5V micro-controller and 3.3V micro-controller. BulletPoint3 : Designed with holes for fixing with bolt, convenient to install. BulletPoint4 : Convenient program control, single chip microcomputer high and low level can make it sound, better than a passive buzzer. BulletPoint5 : This active buzzer has internal oscillation source, so it will alarm as long as being energized.
