About this product
A 0.5 W, 8 ohm trumpet-type speaker for small audio projects, toy electronics and alert sounds. It is best driven by a small amplifier or audio module rather than directly from a microcontroller pin. The listing states a 36 mm diameter in the description and 40 mm in the title, so check the dimensions before fitting it into an enclosure.

Frequently asked questions
Can I connect this speaker directly to an Arduino pin?
It is not recommended. A direct pin connection gives weak and distorted sound and can overload the pin. Use an amplifier or audio module between the microcontroller and the speaker.
Does 8 ohm match common small amplifiers?
8 ohm is a common load rating for small audio amplifiers. Confirm that the amplifier's specification lists 8 ohm loads and does not exceed the 0.5 W rating of the speaker.
