5v DC PCB Buzzer

These 5v DC PCB Buzzer  PCB to make them buzz, instead, you need a microcontroller like an Arduino to create an audible frequency for the buzzer.

This is great if you want to create a chime or melody for a buzzer.

If you are looking for a buzzer that you just add 5V to make it buzz you are looking for an active buzzer like this one 5V Active buzzer

Apply 3V to 5V to this piezo buzzer module and you’ll be rewarded with a loud 2KHz BEEEEEEEEEEEEEEEEEP. Unlike a plain piezo, this buzzer does not need an AC signal.

Inside is a piezo element plus the driver circuitry that makes it oscillate at 2KHz.

The piezo buzzer is 5V TTL logic compatible and Breadboard friendly pin spacing.

This buzzer is ideal when you need to fit a buzzer in a small place. It has its own built-in drive circuit. It offers low current consumption. Used in manufacturing applications such as laptops, alarms, pagers, etc.

Great for use as part of a Code Practice Oscillator.

Specifications:

• Operation Voltage: 3-5V DC
• Current: <25mA
• SPL: 85dBA/10cm
• Frequency: 2,300Hz
• Color: Black
• Operating Temperature: – 20° to +65°C
• Weight: 2.4 gram
• Size: 1.2cm diameter x 1cm tall (0.47″ x 0.39″)
• Pin Spacing: 7.6mm

Note: The piezo buzzer is polarized, meaning that power must be applied to the correct pins. On the top of the case, there is a plus (+) sign to indicate the anode connection pin.
