The BBC announces its intention to give away 1 million Micro Bit to British schoolchildren a few months ago, but at the time, the specifications were not completely frozen. The broadcaster has now finalized the design which is based on an ARM Cortex M0 micro-controller.
Micro Bit board specifications:
- ARM Cortex M0 micro-controller (Nordic Micro nRF51822 Bluetooth SoC)
- 5x holes for 3V, GND, and 3 GPIOs
- 2x user buttons, 1x reset button
- 25x red LED indicator lights in a 5×5 matrix
- Connectivity – Bluetooth LE
- Sensors – Compass, magnetometer, accelerometer
- USB – 1x micro USB port for port and programming
- Power – 5V via USB or battery port to connect two AAA batteries
- Dimensions – 4cm x 5cm
On the software side, the BBC has partnered with Microsoft to develop a web based, drag and drop interface for programming called TouchDevelop. Samsung is also involved in the project as they are developing the Android app, and an iOS app is also planned.
The BBC will send 1 million pieces of the board to schools in the UK this autumn, but they also plan to sell the board to the general public, although pricing and availability information is not available yet.
