BBC microbit

BBC micro board: bit microcontrollers use Nordic nRF51822 ARM Cortex-M0 chip with Bluetooth Low Energy on board. Many of the NXP / Freescale are KL26Z (USB On-The-Go), MMA8652 (3-axis accelerometer) and MAG3110 (3-axis magnetometer). There are also 25 LEDs arranged in 5x5 array. Battery connector and 23-pin edge connector are GPIO such as Digital I / O Analog Input PWM Serial I / O SPI and I2C.

Many NXP / Freescale include the KL26Z (USBOn-The-Go), the MMA8652 (3-axis accelerometer) and the MAG3110 (3-axis magnetometer). There are also 25 LEDs array5x5, two buttons, a Micro USB port, a JST battery connector And 23 pin edge connector are GPIO such as Digital I / O Analog Input PWM Serial I / O SPI and I2C.

BBC micro board: Bit is a board from the British BBC project partnering with Partner to manufacture computer boards to support digital literacy education. In the past, the BBC used the BBC Micro board in 1980 to make the start of computer-based learning.

The development of the program is through an Online IDE, with a choice of blocks and JavaScript learning. JavaScript Blocks Editor JavaScript Blocks Editor and JavaScript Blocks Editor (PXT)

(Https://pxt.microbit.org/) or write Python with the Python Editor (http://python.microbit.org/editor.html).

When finished, the file will be downloaded from the website. Then upload it to the board when you plug the board into the computer (Windows or Mac) to see the board as a MICROBIT Drive to copy the program files into it. For details, refer to the Quick Start Guide.

BBC micro board: Composite bit

Nordic NRF51822 is a 32-bit ARM Cortex-M0 microcontroller. Clock frequency 16 MHz, Flash memory 256 KB, 16 KB RAM with 2.4 GHz Bluetooth Low Energy (BLE). Clock between 16 MHz and 32,768 KHz.

NXP / Freescale KL26Z ARM Cortex-M0 + 48 MHz clock frequency acts as USB 2.0 OTG communicates with the main chip and converts the board voltage to 3.3 volts when powering up or programmed via USB.

The NXP / Freescale MMA8652 is a 3-axis accelerometer sensor with 3-axis accelerometer. Connected via I2C

NXP / Freescale MAG3110 is a 3-Axis 3-axis magnetometer connected via I2C.

Micro USB connector for power supply and computer to upload program.

The JST Battery Connector accommodates 3 volts direct current.

The 23-pin connector on the edge of the two-sided PCB is pinned to the following: 25 LEDs are arrayed in 5 rows of 5 rows.

The BBC micro: bit is a pocket-sized computer with motion detection, built-in compass and Bluetooth technology, which was given free to every child in year 7 or equivalent across the UK in 2016.

A collaboration between 29 partners, the BBC micro: bit is the BBC's most ambitious educational initiative in 30 years, with an ambition to inspire digital creativity and develop a new generation of tech pioneers.

The UK currently faces a critical skills shortage in the technology sector and the BBC and partners aim to help change that.

In the 1980s, the BBC Micro introduced many children to the BBC for the first time and the BBC: Make it Digital Initiative, will build on the legacy of the project for the digital age.

It aims to inspire young people to get creative with digital and develop core skills in science, technology and engineering.

Coding in seconds

"We happily give children paint brushes when they're young, with no experience - it should be exactly the same with technology," Sinead Rocks, Head of BBC Learning said.

The BBC micro: bit is all about young people learning to express themselves digitally, and it's their device to own.

It's our most ambitious educational initiative for 30 years. It is ours to connect to everything from mobile phones to plant pots and Raspberry Pis, this could be for the internet-of-things what the BBC Micro was to to British gaming industry. "

It measures 4cm by 5cm, is available in a range of colors, and designed to be fun and easy to use. It can be coded with something simple in seconds - like lighting up its LEDs or displaying a pattern - with no prior knowledge of computing.

It also connects to other devices, sensors, kits and objects, and is a companion to Arduino, Galileo, Kano, LittleBits and Raspberry Pi, acting as a spring board to more complex learning.

Each element is completely programmable via easy-to-use software on a dedicated website microbit.org, that can be accessed from a PC, tablet or mobile.

A personal area on the website allows users to save and test the creations in a simulator before they are transferred to the micro: bit, and the tools available scale is to be as complex as ideas, imagination and skills require.

Key features of the micro: bit

25 red LEDs to light up, flash messages, create games and invent digital stories.

Two programmable buttons activated when pressed. Use the micro: bit as a games controller. Pause or skip songs on a playlist.

On-board motion detector or "accelerometer" that can detect movement and
