Hear the good news! This wee speaker is a great addition to any audio project where you need 8 ohm impedance and 1W or less of power. We particularly like this speaker as it is small and comes with nice skinny wires with a connector on the end. It has a handy "Molex PicoBlade" 1.25mm pitch 2-pin cable, which makes plugging into a board easy. Or you can cut off the connector and just solder/clamp onto the wires directly.
This speaker will work perfectly with our HalloWing M0 Express - it even snaps into the speaker connector onboard. But you can also use it with any of our mono audio amps, such as the PAM8302 or MAX98357A mono class D amplifiers.
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.
