You can now buy BBC micro:bit board for $19

BBC recently distributed micro:bit boards to UK schools to get student interested in electronics and help them learn more about this subject, but so far it was not for sale to the general public, but this has now changed since the British broadcaster now launched the board for 13 GBP (~$19) via Element14/Farnell and others distributors. The board is powered by Nordi Semi nRF51822 SoC with ARM Cortex M0 micro-controller and Bluetooth LE connectivity, features motion sensors, plenty of LEDS, a few buttons, a micro USB connector for power & programming, as well as a header for LiPo batteries. There are various ways to program the board either interpreted languages such as Python or JavScript, or graphical drag and drop programs such as Microsoft Block Editor. All technical details and example projects available on Micro:bit official website. Beside the board only, several kits are being offered included micro:bit Go with […]

BBC Micro Bit Educational Board Features nRF51822 ARM Cortex M0 MCU

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 […]
