The novelty of micro:Bit for a more lively introduction to technology for children.

The micro:bit is a pocket computer that can be encoded, customized and controlled for the implementation of digital ideas and games. It measures just 4x5cm and features a fun and easy to use design, so users can create anything from games and animations to slick stories at school, at home or anywhere - all it takes is imagination and creativity. It is fully programmable. This means that each of its LEDs can be individually programmed as can its buttons, inputs and outputs, accelerometer, magnetometer, Bluetooth 5.0 technology, microphone and speaker.

It contains a quick start guide in the same package.
