DEVELOPMENT BOARDS
AND ACCESSORIES
This mini magazine and all its contents are made by makers, for makers like you! Find out more about the
newest micro:bit ® accessories and get inspired by cool projects. Learn how to program your micro:bit by using
different platforms and try out some interesting exercises. What are you waiting for? Let’s get started!
PROJECTS
Because the possibilities with a micro:bit
are endless, it is often difficult to know
what project to start with. And that’s
where we come in! To help you out, we
developed different types of projects with
simple explanations and sample code.
In this mini magazine, we will introduce you
to some of these neat projects, but you can
find all tutorials on manuals.velleman.eu.
LEARN EXERCISE
Whoever said
learning is not
fun, never learned
about micro:bit!

magazine!
Practice your
programming and
electronic skills
with some simple
but fun exercises.
Find them throughout
this mini magazine
and expand your
micro:bit techniques.

The BBC micro:bit
is a must for
everybody who wants
to get started with
or is inspired by
programming.
It has an ARM-based
embedded system. It
is compatible with
different coding
languages starting
from Block Editor
& mobile apps for
the starters to
Python for the more
advanced users.
You can connect it
to other devices
such as Raspberry PI
through its 20 pin
edge connector.
The built-in compass
together with the
accelerometer and
motion detector
ensure that the BBC
micro:bit has endless
possibilities.
The BBC micro:bit is
battery operated so
perfectly suited as
a mobile solution.
JAVASCRIPT BLOCKS EDITOR (PXT)
Micro:bit’s new JavaScript editor makes it easy to
program your micro:bit in Blocks and JavaScript, along
with great new features like peer-to-peer radio.
PYTHON EDITOR
The Python editor is perfect for those who want
to push their coding skills further. A selection
of snippets and a range of premade images and
music give you a helping hand with your code.

POWER:BIT SHIELD FOR MICRO:BIT
VMM005
This power module is an extension board for
your micro:bit, powered by two batteries so
you can use it anywhere you want! There’s
also an onboard buzzer that you can use
as an extra output. For instance; to make
your micro:bit buzz when it starts up!
Use your
micro:bit
on the go!
FEATURES
• export micro:bit pins P1, P2, 3V & GND
• onboard buzzer controlled by micro:bit ® P0 port
SPECIFICATIONS
• working voltage: 2.7 V - 3.3 V
• battery: CR2025 or CR2032
• dimensions: 42 x 52 x 5 mm

EXERCISE
MAKE A MICRO:BIT
CONTROLLED FAN
The ideal project for summer break or when you
need to cool down! For this project, you will need to use
the motor shield in
combination with the propellor and the mini motor
from the micro:bit starter kit.
Tip: create a cool case for the fan by using
some cardboard or a 3D printer!

the tutorial
on manuals.

MOTOR SHIELD FOR MICRO:BIT
VMM006
This motor shield is compatible with
micro:bit ® and can be used to drive
2 DC motors at the same time. On top
of that, you don’t lose your micro:bit ® ’s 14 channel I/O ports
because this little motor shield extends them. The motor driving
chip is a TB6612 and drives a maximum of 1.2 A current.
SPECIFICATIONS
voltage range: 6-12 VDC • maximum output current: 2 x 1.2 A •
extendable digital I/O ports: 12 • extendable analogue I/O ports: 3

MICRO:BIT EDUCATION
SMART ROBOT KIT
VMM500
This easy kit comes with all the
parts you need to build a working
robot cart! Combine it with
another micro:bit to control it
and/or add a pen to make a doodle
bot!
LEARN
WHAT DOES I/O STAND FOR? AND WHAT IS IT?
I/O stands for Input and Output! An input is a device that sends information to a computer system for processing, and
an output device reproduces or displays the results of that processing. Input devices only allow for input of data to
a computer and output devices only receive the output of data from another device. In our case; the micro:bit is the
computer system which we program and an input can be a temperature sensor or microphone because these are devices that can
receive information. The output can be a servo motor or an LED because they send out information like movement and light.
You’re welcome!
4 CHANNEL RELAY MODULE FOR MICRO:BIT
VMM400
FEATURES
• BBC micro:bit ® interface connector
• indicator LEDs for relay
output status
• 3.3 V regulator on board
This 4-channel relay interface
board can control various
appliances and other equipments
with high current.

PROJETS
MAKE DIFFERENT TEMPERATURE DISPLAYS
Keep a good eye on your room’s temperature by using some
simple I/O’s from our micro:bit starter kit!
In this project you can display the temperature in two different ways.
Either use the LED ring to burn red when the temperature exceeds +
24°C and blue when it’s colder. Or for a more precise display, you
can use the servo shield and get creative with cardboard to make a
scale. The servo’s arrow will hence tell you what temperature it is.
Find the sample code and all explanations on
manuals.velleman.eu and impress your teachers and
parents with this cool science project.

KEEP YOUR PLANTS HAPPY WITH MICRO:BIT
No more dead plants on our watch! With this ingeniuos
project, you will be able to read whether or not your plant
is moisty enough or if it is in need of some water!
Use the soil moisture breakout board to inspect your plant’s
soil and make it report to your micro:bit. If the plant is not
happy and in desperate need of water, the red LED from the
breakout board will light up and the OLED breakout board will
tell you what’s wrong. If all is well, the green LED will shine
bright. All these components can be found in the micro:bit
tinker kit and the tutorial is available on manuals.velleman.eu!
