Listen up! This 1.1" (~30mm) diameter speaker is the perfect addition to any breadboard-based audio project where you need 8 Ohm impedance, and have 0.2W or less of power. The two pins are 15mm / 0.6" apart and fit perfectly in a breadboard or perfboard. This speaker has a durable protective plastic casing that's still lightweight.
Works great with our Wave shield or class D amplifier board (just be careful not to overdrive it)
Jargon buster
Plain-language definitions for the technical terms used above.
- Impedance
- Impedance is the total opposition a component or circuit presents to alternating current, measured in ohms, combining resistance with frequency-dependent reactance. It appears in many contexts, such as matching a speaker's impedance (for example 4 ohm or 8 ohm) to an amplifier or the input and output impedance of signal circuits, and a correct match helps avoid weak signals, distortion or damage.
