The Grove Speaker Plus is a plug-and-play speaker module for microcontrollers, pairing a driver board with a separate speaker. It plays tones and short sound effects driven by a PWM signal, so you can code melodies or sound cues. Unlike the original Grove Speaker, the speaker is detachable and replaceable, and an onboard potentiometer sets the volume. It suits makers and students building buzzer-style projects, not anyone after hi-fi audio.

The Grove Speaker Plus is a speaker module made up of an amplifier driver board and a separate speaker. The speaker produces different tones depending on the input frequency, and it is controlled with a PWM signal.
The speaker is separate from the board and can be replaced, so you can connect a loudspeaker of your choice. An on-board potentiometer adjusts the output volume. The module uses a plug-and-play interface.
It can be used to create sound effects, play songs, or build a music box with simple coding or existing music code. Compared with the previous Grove Speaker, it has a better-quality speaker.
