Product Description

Kitronik 0.25W 8 Ohm 40mm Thin Speaker

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. We have also tested this speaker with our mono amp kit and it works like a charm.

This 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 microbit as a present as well as part of the card.


  • Requires: Solder & Soldering Iron
  • Diameter: 40mm
  • Thickness: 4mm

Awesome service with super fast delivery. The chat option really helped me choose the products, know they were in stock and would be delivered in time. The items were posted the same day and I couldn't believe it when they arrived from Perth to Melbourne in 3 days! Thanks for your wonderful support - our students were able to complete their robotic projects in time.
