BBC Micro Bit: the credit card-sized computer


The BBC plans to give a million tiny computers away to 11-year old students at UK schools this fall. BBC has unveiled the final design for the device it calls the Micro Bit.

There are two buttons on the device that can be used to control it, plus a reset button.

The BBC, which has just accepted the £650m annual cost of providing free licence fees to over-75s, would not say how much it has invested in the 4cm by 5cm micro:bit, which has been developed with 28 partners including Microsoft, Samsung and the Wellcome Trust.

Students can create programs using a website, test them online, and then transfer them to the Micro Bit using a USB or Bluetooth connection. You can also connect a Micro Bit to an Arduino, Rapsberry Pi, or Intel Galileo board if you want to use it for more complicated functions.

According to the BBC, you could use the built-in sensors to turn the Micro Bit into a metal detector, use the Bluetooth connection to turn it into a remote control for a DVD player or other devices, or make a simple video game controller. The design’s been refined a bit since the BBC first announced the project. The buttons and motion sensor are new, but the developers have dropped plans to include a built-in battery. If you want to use the Micro Bit on the go, you’ll need to attach a battery pack with AA batteries.

The new Micro Bit has a much simpler design than the original BBC Micro, and it’s a lot cheaper. But it could help kids learn the basics of programming at an early age.
