Easy Funny Affordable
The Elecrow Starter kit for Micro:bit is designed for people who are at the doorstep of learning
electric modules and programming knowledge and bring numerous creative possibilities for
you to dig out and help you enter a wonderful electronic world. This kit includes more than 20
modules like the buzzer, light sensor, servo, ultrasonic ranging sensor, and OLED, etc. The kit
also provides you plenty of fun experiments so you can learn how the electric modules work
and use it to build innovative works and plan out unique projects. In addition, the kit also
focuses on stimulating children's creativity so that they can continue to move forward rather
than stagnate after completing their work. We never allow complicated jumpers to prevent
children from learning about the electronic world and programming hobbies and interests,
and we vowed to change it. Therefore, we have equipped this starter kit for Micro:bit with our
plug-and-play crowtail series of electronic modules to make you realize the electronic works in
the mind quickly and easily.

Micro:bit is a pocket-sized computer that lets you get creative with digital technology. You can
code, customize and control your micro:bit from anywhere! You can use your micro:bit for all
sorts of unique creations, from robots to musical instruments, the possibilities are infinite. The
micro:bit compatible with a number of online code editors across a number of different
languages, such as
Blocks
,
JavaScript
,
Python
,
Scratch
, and etc. This guide will focus on
Makecode, a block or JavaScript-based environment developed by Microsoft.
LED Array: The micro:bit has 25 individually-programmable
LEDs, these 5x5 red LEDs form a very small section of a screen,
and display information like words, numbers, and pictures
through a combination of ON and OFF LEDs.
Edge "Pins": The gold tabs at the bottom of the board are
for hooking up external components. The tabs with larger
holes can be easily used with alligator clips to prototype
quickly!

Components on the board
2
A/B Buttons: There are two buttons on the front of the
micro:bit - button A and button B, you can detect when these
buttons are pressed, allowing you to trigger code on the
device. You can detect events such as a single press, a double
press, and a long press by programming.
Light Sensor: The LED screen works as a basic light sensor by
reversing the LEDs of the screen to become an input which
allows you to detect the ambient light.
5
Temperature Sensor: The Microcontroller doubles
as a temperature sensor! The temperature sensor
transforms the temperature in the ambient
environment into digital signals that can be read by
the micro:bit for calculating the current tempera-
ture of the device.
Compass: The compass detects the earth’ s magnetic field,
allowing you to detect which direction the micro:bit is facing.
The compass has to be calibrated before it can be used.
Calibrating the compass ensures the compass results are
accurate.
Accelerometer: The accelerometer measures
the acceleration of your micro:bit, it can track
motions like tilt, free fall and shake.
3
Bluetooth: The Bluetooth Low Energy antenna
allows the micro:bit to send and receive Bluetooth
signals, you can wirelessly communicate between
micro:bit and phones, PCs, or tablets. You need to
pair your micro:bit with another device before using
the Bluetooth antenna.
Radio: The radio feature allows you
to communicate wirelessly
between two or more micro:bits.
Quick start
Step 1. Connect it
Connect the micro:bit with your computer via a USB cable, then your micro:bit will show up on
your computer as a drive called “MICROBIT”.
Write your micro:bit code by using the official online editor https://makecode.microbit.org/
Step 2. Program it
4
The left part is a simulator, which will simulate the work of micro:bit after finishing the
program. The middle part is our command area, there are various program blocks we need.
The rightmost area is the script area, you can drag and drop instructions into this area to form
your program. Drag and drop some blocks and try your program out in the Simulator in the
Makecode Editor, the example below shows you how to program a smiley face.
Step 2-1. Select “on start” block in the command area, and drag it out to place it in the script
area.
Step 2-2. Drag out the “show icon” block and place it inside the “on start” block.
Step 2-3. Pick a name for your program, We’ll name this project as “Smile Face”.

Click the Download button in the editor, And then it will download a “hex” file that your
micro:bit can read. Once the hex file has downloaded, copy it into your micro:bit like copying
a file into a USB drive.
The micro:bit will pause and the yellow LED on the back of the micro:bit will blink while your
code is programmed, the code will run automatically once it’s finished. Then look at your
micro:bit, the screen will show a smiley face.
Note: The micro:bit drive will automatically eject and come back each time you program it,
but your hex file will be gone. It can only receive hex files and won’t store anything else.
There is no wire needed if you use Bluetooth to send the
code to your micro:bit from your mobile device. What
you need to do is to make sure your micro:bit is powered
up and within easy reach of the phone or tablet while
running the App. There are two types of APPs available
for micro:bit which are based on Microsoft Makecode
languages and Javascript: respectively micro:bit
companion app and Windows 10 APP.
The micro:bit app is the essential companion to the BBC
micro:bit, available for iOS and Android. Download the
official micro:bit app for Android or iOS from the app
store, the app contains handy instructions on how to
pair your micro:bit with the app.
The Windows 10 APP has a few extra features over the editor at makecode.microbit.org that
will work on micro:bits with up-to-data interface firmware: automatically program your
micro:bit over USB, without needing to drag-and-drop the file onto the micro:bit drive;
directly read serial data from your micro:bit for data logging and other fun experiments.

What is Crowtail
Crowtail-Base shield for Micro:bit
Welcome to the world of Crowtail! Crowtail is a modular, ready-to-use toolset, it takes a
building block approach to assemble electronics. It simplifies and condenses the learning
process significantly. In our Crowtail repository, there are over 150 Crowtail modules and
Crowtail shields!
The Crowtail products are basic-functional modules that consist of a Base Shield and various
modules with standardized connectors, each Crowtail module has its specific functions, such
as light sensing and temperature sensing. It will satisfy all you need for your project!
Crowtail is a series of products that we made to solve the messy jumper when connecting
electronic circuits. It consists of a Base Shield and some basic Crowtail modules, which help
you create small, simple, and easy-to-assemble circuits. In other words, when you use Crowtail,
your electronic project will not be messy wiring. Instead, it will be simple and easy to manage
an electronic project!
The Crowtail-Base shield for Micro:bit is the core part of this
kit, it acts as a bridge between Micro:bit board and Crowtail
modules. You can plug and then play with Crowtail
modules and micro:bit through this base shield, which
allows you to create more interesting and innovative works
with micro:bit. This shield integrated 6 crowtail connectors
and 2 crowtail UART/I2C connectors onboard. So you can
use plenty of crowtail sensors. All you need to know is that
there is no need for any soldering or jump wire about
Crowtail.
In addition, there is a power port, from which you can draw 3.3V/5V/12V three voltages! This
means that when you use a module such as a motor, you no longer need an external drive!
