The BBC has revealed the final design of the Micro Bit, a pocket-sized computer set to be given to about one million UK-based children in October 2015.

The device - which features a programmable array of red LED lights - includes two buttons and a built-in motion sensor that were not included in a prototype shown off in March. Another design change means the product no longer has a slot for a thin battery, which maybe compromise is appeal for wearable device application.

An add-on power pack, fitted with AA batteries, will be needed if required to be used as a standalone product.

"We all know there's a critical and growing digital skills gap in this country and that's why it's so important that we come together and do something about it," BBC's director general Tony Hall a launch event in London.
