Buzzer PCB 5V - Active, Continuous Beep

This is a tiny 12 mm continous beep buzzer. These are great since they don't need any type of amplifier, and can be driven directly by a digital I/O on any microcontroller. This buzzer will beep when 5 volts is applied it. Some apply in their RFID video to alert when a card was properly scanned.
