The Amp:bit is the easiest way to connect a speaker or headphones to your BBC micro:bit. The Amp:bit plugs on to the edge of your micro:bit and gives you the option of plugging headphones or speakers into the provided headphone jack, or you can solder speaker wires directly to the provided pads. The spacing is perfect for our 2 pin 3.5mm screw terminals.

If you have a speaker connected to the speaker pads, the speakers will automatically mute when something is plugged in to the headphone socket. We also give you a volume control wheel so you can adjust the volume whenever you like.



The Amp:bit also works great with our 1up:bit game controller!

AMP:BIT class D amplifier
Wednesday, 4 October 2017  |  John

This is one of the many add-ons for the micro:bit that I have purchased from Proto-pic. It has been designed and built to the very high standard that we have become accustomed to from this company.

Being a musician, amongst other things, I was keen to see how the micro:bit played music and also speech using the various coding methods available. There are terminals at each end of the board to connect a small loudspeaker or mono headphones. The speaker needs some very simple soldering via short leads to the board but the headphones are connected via a 3.5mm socket. Although I have a collection of headphones and earphones at hand I was keen to use a safer method of listening to the output. There is a very adequate volume control on the board but I couldn’t trust children not to fiddle with this. A search on the web came up with a mini pillow speaker which conveniently had a 3.5mm jack a the end of a decent length of cable. I bought mine from Amazon for £5.77 and it was called Elegiant. This pillow speaker is a perfect partner for the AMP:BIT, the sound level set at maximum with the on-board volume control would probably be enough for classroom use.

I have had some interesting results with this combination and have been impressed, even with the speech capabilities of the micro:bit.

I am particularly pleased with the AMP:BIT and pillow speaker combination. Can I recommend that you download some Micro Python code cleverly written by BBC micro:bit expert Nicholas Tollervey to show off this combination. It is the song ‘Daisy, daisy’ as was sung by the HAL 9000 Computer in the film 2001: A Space Odyssey. The micro:bit performs this superbly through the very nice little AMP:BIT and speaker. A YouTube demo of this can be found at which also gives a link in the accompanying text to the website where the program can be downloaded from. You will be no doubt be impressed to hear actual words being sung using these devices! (

Great Addition to Micro:Bit
Monday, 21 August 2017  |  Jason

Simple to fit . No extra programming required!
Makes getting sound from the Micro:Bit very simple - No more croc clips !!

Only minor wish is that the 3.5mm headphone socket was stereo.When using headphone sound only appears in one ear.
I realise the Micro:Bit is Mono & I can use an external adapter so not really a problem!!!
