Frequently asked questions
Can I connect it to a 5 V Arduino pin?
It is rated for 3 V, so use a 3.3 V output or drive it through a transistor with a series resistor when using 5 V. A 25 mA rated current is above the recommended per-pin current for many boards, so a transistor is the safer choice.
How loud is it?
The minimum sound output is 90 dB measured at 10 cm, which is loud enough for alarms and status tones in small projects.
