This allows the micro:bit to detect the current ambient temperature, in degrees Celsius.

The micro:bit has 25 individually-programmable of these, allowing you to display text, numbers, and images.

There are two of these on the front of the micro:bit (labelled A and B). You can detect when they are pressed, allowing you to trigger code on the device.

This allows you to detect ambient light.

This detects the earth's magnetic field, allowing you to detect which direction the micro:bit is facing

This feature allows you to communicate wirelessly between micro:bits.

This allows you to connect the micro:bit to your computer via a micro-USB cable, which will power the device and allow you to download programs onto the micro:bit.

This allows the micro:bit to wirelessly communicate with PCs, Phones, and Tablets.

This measures the acceleration of your micro:bit; this component senses when the micro:bit is moved.
