Datasheet

The BBC micro:bit is a pocket-sized computer that lets you get creative with digital
technology. Each order contains just the micro:bit board. 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 and more. At half the size of a credit card,
you will be surprised at the amount of hardware each board is equipped with, including
25 red LED lights that can flash messages. There are two programmable buttons that
can be used to control games or pause and skip songs on a playlist. The micro:bit can
even detect motion and tell you which direction you’re heading. It can also use Bluetooth
Low Energy (BLE) to interact with other devices and the Internet.
Taking a closer look at the front of the board, you can see the 5x5 LED array that you
can use as a light sensor, a tiny screen to draw on, display words, numbers and other
information, and the two programmable buttons! On the back of the board you will find
the brains of the micro:bit, a 16MHz, 32-bit ARM Cortex-M0 microcontroller with 256KB
Flash, 16KB RAM and a built-in temperature sensor. Additionally, the back of the
micro:bit is populated by an accelerometer, compass and Bluetooth Smart antenna, as
well as a microUSB and two-pin JST connector for different power options. Finally, at the
bottom of the board you will find 20 gold-tabbed edge pins and five ring connectors (three
for digital/analogue I/O, two for power and ground) for hooking up external components.
The tabs with larger holes can be easily used with alligator clips to prototype added
components quickly.
