What is a micro: bit？

The micro: bit is only half the size of a credit card. It is equipped with a 5×5 programmable LED matrix, two programmable buttons, an accelerometer, an electronic compass, a thermometer, Bluetooth, a new touch-sensitive logo, a microphone, a speaker, and other electronic modules.

Meet the new micro: bit V2.2 – an improved version of the original micro: bit featuring a built-in speaker, microphone, touch sensor, and more computing power! This listing is for the single micro: bit V2.2 board.

This listing is for the micro: bit V2.2 board with Micro:bit IO:bit Expansion Board , which includes:

The NEW micro: bit V2.2

The BBC micro: bit V2.2 is a pocket-sized computer that you can code, customize, and control to bring your digital ideas, games, and apps to life.

It’s a fantastic way to introduce budding coders to the wonderful world of computer programming. With the easy-to-use online code block editor and simple crocodile clip-friendly board, coding fun projects and using electronic components is easier than ever.

Great for learning!

Detects motion and direction – create games that use shaking motions or directions with built-in sensors and compass
Control your projects using the 2 buttons clicky buttons – make games, control robots, count things!
Tap the capacitive button as an input for your projects – stop/start the music, start a timer, run a program, or whatever you decide!
Flash messages, your name, or animations across the 25 programmable lights
Connect the BBC micro: bit to your phone using Bluetooth to take selfies without touching your phone
Use the on-board speaker to play sounds or music as part of your project
Easy to code with the online drag-and-drop code block editor

Micro:bit IO:bit Expansion Board

The IO expansion module is designed to work with the micro:bit educational board. There are 20 GPIO pins on the board. Each GPIO has VCC and GND power pins, which makes it much easier to connect additional elements, e.g. sensors. The module is equipped with a voltage stabilization circuit with a jumper for selecting the operating voltage of 3.3 V or 5 V, it has a built-in buzzer and a 4-pin I2C connector. The board can be powered by the DC connector with the voltage ranging from 6 to 12 V or by the microUSB connector. The module will work in many projects using micro: bit that require the connection of additional sensors or display.
