This simple yet effective Grove buzzer module is a standard board mounted piezo sounder. It can be added to a digital output and will emit a tone when the output is high. It can also be attached to an analogue pulse width modulation (PWM) output and can generate various tones and effects. It has an operating voltage of between 3.3V - 5V and the board is fitted with a standard Grove connector.

Features:

Add sound to your Grove projects with this plug and play module.

A piezo buzzer module that can used with both digital and analogue outputs.

It has an operating voltage of between 3.3V - 5V.

The board featured a standard Grove connector.

Length: 24mm, width: 20mm, height: 9.8mm

Requires:

A Grove compatible interface.

These Miniature Buzzers are a low cost miniature transistor oscillator 6V buzzer with flying leads. They have a single-tone frequency of 400hz and a sound output of 75dB @ 200mm. They are rated for 4V - 8V (6V nominal) and a current of 25mA and the driver circuitry is built in. These buzzers are supplied as a pack of 10.

The buzzer unit is L23mm x W17mm x H15.5mm, with fixing centres at 27.5mm, which gives a total length measurement of 33.5mm. The colour-coded (red & black) flying leads are 100mm. To ensure optimum performance and to protect the buzzer, ensure that the supply (e.g. batteries) is connected in the correct configuration.

The MI:sound board is a speaker board for the BBC microbit. It features on-board; speaker, CR2032 battery holder, thumbwheel volume control and an easy access on/off switch. The MI:sound board can either be powered by the CR2032 battery (provided) or via the micro:bit USB or JST connections. It has been designed to work with micro:bit V1 and micro:bit V2.

The speaker on MI:sound can be used in conjunction with the micro:bits onboard speaker or instead of. The micro:bit speaker can be turned off as there is a command/block for that in the MakeCode editor. Why would you want to? Volume! MI:sound's speaker is loud, and the potentiometer gives you control over its volume without the need to head back into the code. Super convenient!

To use the MI:sound speaker board, the BBC micro:bit should be attached using the supplied bolts, spacers and nuts. Only Pin 0, 3V and GND need to be connected. Crocodile clips can also be used.

When assembled, the MI:sound board is connected directly to the 3V, GND and P0 connections on the micro:bit. The 3V and GND connections provide power to the micro:bit and the built in buzzer is connected to P0, which is the default output pin when using the audio functions in the MakeCode software. The board has an easy to access on/off switch, which makes it easy to turn a project on and off.

Like the MI:power board, MI:sound offers an elegant solution for micro:bit projects on the move. Both boards provide power to micro:bit, feature an on/off switch and allow you to output sound. Sound though is a much bigger feature on the MI:sound board. Where the MI:power board features a buzzer, MI:sound has an actual speaker with a thumbwheel volume control. Not only is the speaker more versatile than a simple sounder, it is also much much louder. So, in brief; the MI:power board is more compact and MI:sound is better for projects where sound is an integral part of the project.

Features:

Power your BBC micro:bit from a stylish PCB.

It features an on-board speaker and it's loud!

There is a thumb wheel operated potentiometer volume control.

There is an onboard CR2032 battery holder.

The board features easy access on/off switch.

Designed to work with micro:bit V1 and micro:bit V2.

Contents:

1 x MI:Sound speaker board for BBC micro:bit V2.

3 x 12mm M3 Countersunk Screw.

3 x M3 Steel Nuts.

3 x Nylon Spacers.

1 x CR2032 Coin Cell.

This is the perfect speaker for projects that produce sound but where space is tight or where the speaker needs to be discreet. These speakers work well with the BBC microbit; you can code the microbit to play music or emit a beep as an alarm and this little speaker will do an admirable job.

This a 0.25W, 8ohm speaker is only 40mm in diameter and just over 4mm thick making it very similar in size to those found in talking greeting cards, you could even design a microbit talking greeting card that has the built in micro:bit as a present as well as part of the card.

Features:

8ohm speaker that is ideal for use with the BBC microbit.

4mm thick, making it ideal for use as a discreet speaker.
