The BBC micro:bit  is a small un-cased circuit board with a display made up of 25 LEDs; a couple of buttons and some sensors. Crucially it has a micro USB socket that allows you to connect it to your computer both to power it and to send programs to it. The micro:bit has large connectors designed to accept alligator clips so that you can connect extra electronics.

MonkMakes have a number of products for the BBC micro:bit and have more in the pipeline. Our flagship product is the Electronics Starter Kit for micro:bit. Click on the headers below to find out more about these products.


Electronics Starter Kit for micro:bit.

With this kit, you get everything you need to start learning about connecting electronics to your micro:bit in an accessible and easy manner. Everything is connected using the supplied alligator clips, so no soldering required. This kit suitable for children as young as 10 with some adult help.

The kit uses three expansion boards for the micro:bit that are designed to be connected together in various configurations using alligator clip leads. These boards are also available to buy separately.


A LiPo battery and charger board that charges automatically while you use your micro:bit! This neat solution to your micro:bit’s power needs comes with an acrylic layer enclosure to protect your micro:bit and the Charger for micro:bit.


Animatronic Head Kit FOR MICRO:BIT

This kit provides everything you need (apart from a micro:bit and batteries) to make a talking animatronic head. Its eyes move and the head speaks from a MonkMakes Speaker for micro:bit.

Relay for micro:bit

The MonkMakes Relay for micro:bit is a solid-state (no moving parts) relay that allows an output of a micro:bit to turn things on and off. You can also use it to control the speed of a motor or the brightness of a light bulb.

This relay can be used to switch low voltage devices such as light bulbs, a motor, a small heating element or even a string of 12V LED lighting. The voltage needs to be kept under 16V, but the relay will automatically protect itself against too much current.


Speaker for micro:bit

The MonkMakes Speaker for micro:bit is a neat little amplified speaker that connects to your micro:bit using alligator clips. Despite its small size, this speaker is pretty loud.


Sensor for micro:bit

The MonkMakes Sensor Board for micro:bit allows you to sense sound level, temperature and light level.


RGB LED for micro:bit

The MonkMakes RGB LED is an LED that you can mix colors on to make any color that connects to your micro:bit using alligator clips.



The 7-segment for micro:bit is a four digit 7-segment display for micro:bit. You can use it to display numbers, but it can also display letters and other characters, albeit with the limits imposed by the 7 segments of each digit.



This tiny board has a standard DC barrel jack socket at one end and provides a regulated 3.3V output that you can use to power your micro:bit using the JST battery connector attached to wires coming from the other end of the board.



The MonkMakes Servo for micro:bit board provides a really easy way to attach up to three servomotors to a BBC micro:bit. The board requires a power supply or battery pack to provide 5 or 6V to the servomotors. It includes a voltage regulator that will supply 3V back to the micro:bit, so that you don’t have to power it separately.



The Servo Kit for micro:bit makes it easy to connect up three servomotors from your micro:bit. Not only that, but the kit also comes with three servomotors and a battery box. Just add a micro:bit and batteries and away you go!

CO2 Sensor for micro:bit

This board, designed for use with the Lets Talk Science Living Space Project, provides a CO2, temperature and Relative Humidity measurements to a BBC micro:bit.
