A transistor that will allow other items to be switched where the micro:bit would not be able to. Items such as motors, larger speakers, relays and so forth, up to 1A total load. A current limiting resistor is in the circuit to protect the micro:bit...

A very accurate temperature sensor using a calibrated chip called a TMP36GZ. It is accurate to ±1°C at +25°C. At this temperature it outputs 750mV. It changes by 10mV per °C. The black lead goes on GND, the red lead goes on 3v and the blue lead goes on...

A small microphone with amplifier & threshold setting. It can detect when sound reaches a certain level. It can not detect a particular frequency and there is no support in the micro:bit programming environment at present for it to analyse the...

A small motor that moves it's output arm to a position depending on the signal sent to it with a reasonable degree of accuracy & repeatability. The brown lead with the black croc clip goes on to GND, the yellow lead goes on to the Pin 0, 1 or 2 that...

A 3V Light Emitting Diode as an additional LED. It uses a high brightness low current LED and includes a current limiting resistor to protect the micro:bit’s output. The black lead goes on to GND and the green lead goes on to whichever Pin 0, 1...

A pushbutton on a lead for when you need another pushbutton or you want it away from your micro:bit One lead goes on 3v or GND and the other lead goes on 0, 1, or 2. For advanced applications it is feasible to connect two pins with the pushbutton. It...

Provides a variable voltage to an analog input via a twist knob – a volume control if you will. Can be used for any application where a user input across an analog range is required – for instance changing the frequency of the music output or the speed...

A type of buzzer – it has to be driven by a pulsed output. It’s tuned for around 2kHz when it will be at its loudest but will produce a tone across a wide range of frequencies. In the Block Editor, the black lead goes on to GND and the blue...

Description A small version of the PIR that is used in a typical burglar alarm. It triggers when a warm body passes in front of the detector. It has some range / sensitivity setting capability and the duration of the output can be set. The black lead...

Good for detecting boxes, drawers or doors being opened and much more. The black lead goes on GND, the red lead goes on 3v and the other lead goes on 0, 1, or 2. This item is somewhat polarity sensitive, the red & black leads need...

An external light sensor for all your light sensing needs. The black lead goes on GND, the red lead goes on 3v and the other lead goes on 0, 1, or 2. This item is polarity sensitive, the red & black leads need to be on the correct...

A standard 3.5mm stereo headphone adapter to two crocodile clips for Micro:bit This won’t give you stereo, but it does play in both ears! The black lead goes on GND, the green lead goes on 0. It doesn’t matter if they are put on the other...

A simple buzzer with transistor that can be powered by the micro:bit. Costs more than a headphone adapter but far less than the mini-speaker – its best use is to act as a sounder for an alarm or similar.

Compatible with micro:bit V1 only!   Caution! The BBC micro:bit, and MI:power board are NOT included. This is the ORANGE version of this case. This case has been designed to protect a BBC micro:bit with...

Compatible with micro:bit V1 only! The Kitronik Klip Halo for the BBC microbit breaks out all of the pins from the microbit to pads spaced around the edge of the Klip Halo. The pads have been carefully designed and spaced...

ElecFreaks Micro:bit Breakout Board matches perfectly with the BBC micro:bit pins. Plug in this breakout board for instant access to micro:bit’s GPIO. Features Input voltage: 3.3V, Powered by the edge connector of the micro:bit. Extend all of...
