Crowtail Start Kit for micro:bit User Guide

The BBC micro:bit is a pocket-sized computer that can easily realize your creativity without

much electrical and coding knowledge. There are numerous possibility of creation you can dig
out by micro:bit, from robots to musical instruments. However if you want to create more things,
just 1 micro:bit is barely not enough, That

s why we introduce the Crowtail Start Kit for micro:bit

to you.

The crowtail start kit for micro:bit can make you do a lot of interesting things and brings

endless possibilities to your micro:bit. The core board in this kit is Crowtail- Base shield for
micro:bit,with which you can use plenty of crowtail sensors.All of that you need to know about
Crowtail, there is no need any soldering or jump wire. We have prepared 17 species basic
crowtail modules that let you get started with micro:bit. And we also write 20 lessons to teach
you use the micro:bit with the sensors step by step. Now, let us enjoy them.
