This is a single BBC micro:bit with no accessories, sealed in an antistatic bag. Your BBC micro:bit will come in one of 4 colour schemes, unfortunately it is not possible to specify which colour you will receive.

The BBC micro:bit is a powerful handheld, fully programmable, computer designed by the BBC and a number of partners to encourage children to get actively involved in writing software and building new things that will be controlled by it. Write your code using one of the easy to use editors provided on the BBC micro:bit website, connect your BBC micro:bit to your computer via USB press the compile button in the editor and then drop the downloaded file directly onto your BBC micro:bit. There is also an app for Android devices.

Wirelessly connect and interact with the world around you. Use Bluetooth Low Energy to connect to mobile phones and tablets, take a selfie or drive the music in your playlists.


The BBC micro:bit is the spiritual successor of the BBC Micro of the 1980s, which itself introduced a generation of children to computing. The BBC micro:bit carries on this 30 year tradition and does it 18 times faster and is 70 times smaller than its predecessor.

Based around a 32 bit ARM Cortex-M0 processor, the BBC micro:bit also features on board accelerometer and compass sensors, Bluetooth Low Energy and USB connectivity, a display consisting of 25 LEDs, two programmable buttons and it can be powered by either USB or an external battery pack. The device inputs and outputs are through five ring connectors that are part of the 21-pin edge connector.


  • USB and Bluetooth Low energy connectivity.
  • Compass and Accelerometer.
  • 2 x user assignable buttons.
  • A 25 LED display.
  • 21 pin edge connector.



  • PCB Length: 52mm.
  • PCB Width: 42mm.
  • PCB Height: 11.7mm.

microbit inventors kit resources
Kitronik Inventors Kit Resources
This resource consists of a selection of links to the additional resources that we have created to accompany each of the experiments. Each experiment has a walk-through video that also contains hints and tips designed to help you complete the experiment and to understand how the circuits work, we have also included links to additional code examples.
The Motor Driver Board For The BBC micro:bit V2
As has been highlighted in the most recent BBC micro:bit newsletter, we have just launched a new and improved version of our very popular Motor Driver Board for the BBC micro:bit, The Motor Driver Board V2.
Robot Buggy Part 1 An Introduction
This fun learning resource has been put together to provide teachers with an all in one design and technology challenge that you can set for your students over the course of a term or a year. The resource includes a number of different design and technology aspects; electronics, mechanical assembly, 2D and 3D design, using a laser cutter, using a 3D printer and coding and testing. There are also alternative production methods highlighted in the individual resources.
Coding With The PXT Editor
Robot Buggy Part 6 Coding With The PXT Editor
Martin Woolley explains how he wrote the Robot Buggy code using the Microsoft PXT Editor for the BBC micro:bit. Includes a link to the completed code. Martin not only wrote the code that we use for the remote controlled buggies, he also designed the Bluetooth profile for the BBC micro:bit and wrote and released the micro:bit Blue App, which we used to control the buggys.
The Self Righting Flag
Robot Buggy Part 5 The Self Righting Flag
The last part of our physical design challenge was to design a flag for a capture the flag style game. As with most of the design challenges that this project presented, we had some ideas and discarded the difficult and impractical until we were left with a simple but effective solution.
The 3D Printed Add-Ons
Robot Buggy Part 4 The 3D Printed Add-Ons
When designing the 3D printed add-ons we had two main aims; that they maintained our Robot Wars theme and that they could be printed easily. Our additional goals were to create two team colour schemes and that each buggy had it's own personality.
Creating The Perspex Top Plate
Robot Buggy Part 3 Creating The Perspex Top Plate
We looked at a few different ways of achieving our Robot Wars inspired buggy but quickly settled on keeping the buggy completely intact and cutting a top plate from a perspex sheet. We wanted it to be functional, aesthetically pleasing and also easy to produce. We had six buggies to design and build and only a few days to get them done.
Remote Control Via Bluetooth
Robot Buggy Part 7 Remote Control Via Bluetooth
Bluetooth is the technology that makes the remote control aspect of this project possible, fortunately, the BBC micro:bit comes with Bluetooth functionality as standard. Martin Woolley explains how to pair your Android device with the BBC micro:bit and how to use is micro:bit Blue App to control the Robot Buggy.
line following buggy
Robot Buggy Part 2 The Line Following Buggy
The line following buggy for the BBC micro:bit is a great kit for students to build as it combines several elements of design and technology; electronics, mechanical assembly and coding and it is this buggy that the Robot Buggies are built upon. The kit has relatively few parts and is simple to build, making it a suitable option as a classroom activity.
Use The BBC micro:bit As An Instrument Tuner
Use The BBC micro:bit As An Instrument Tuner
In this tutorial we are going to highlight how easy it is to code the BBC micro:bit as an instrument tuner. We will focus mainly on making a Guitar tuner but we will also provide download links for several different types of tuner.
