BBC micro: bit Go (starter kit)

Description

micro: bit Go (On-the-go Starter Bundle).

micro: bit is a pocket-sized microcontroller designed for kids and beginners learning how to program, letting them easily bring ideas into DIY digital games, interactive projects and robotics. micro: bit comes with a variety of on-board modules, including a 5 × 5 LED matrix (also supports light detection), 2 programmable buttons, motion detector, compass and Bluetooth® Smart module. Additionally, you can attach more modules such as a servo motor, RGB LED lights through five I / O rings or 20 edge connectors.

The on-the-go starter kit comes with a USB cable, 2 AAA batteries and a battery holder, allowing you to upload a program and carry it around right after the unboxing.
micro: bit can be programmed with Microsoft Blocks Editor via graphical editor or JavaScript editor.

Features:
A variety of on-board modules
Expandable for additional sensors or actuators
Graphical drag and drop code editor
Easy and smooth program uploading
Bluetooth wireless programming uploading
Bluetooth wireless communication

Specification:
Microprocessor: 32-bit ARM® Cortex ™ M0 CPU.
A 5 × 5 LED matrix with 25 red LEDs to light up. Each LED is individually programmable and can display animated patterns, scrolling text and alphanumeric characters.
Two programmable buttons. The micro: bit can detect either of its two buttons being pressed and unpressed and can be programmed to act on that or send the information to another device. Use them as a games controller or control music on a smartphone.
On-board motion detector or 3-AXIS digital accelerometer that can detect movement and tell other devices you're on the go. It measures on 3 axes, X, Y, Z, and sends back the data. The micro: bit can react to this data and tell other devices it is moving. The device will also detect a small number of standard actions, eg shake, tilt and freefall. Turn the micro: bit into a spirit level. Use it for motion-activated games. Have your micro: bit light up when something is moved.
A built-in compass, 3D magnetometer to sense which direction you're facing and your movement in degrees. This data can be used by the micro: bit in a program or be sent to another device. The magnetometer could also detect the presence of certain metals and magnets.
Bluetooth® Smart Technology (formerly called Bluetooth Low Energy) to wirelessly communicate with other Bluetooth Smart devices and exchange data and commands. Connect the micro: bit to other micro: bits, devices, phones, tablets, cameras and everyday objects all around.
Five ring input and output (I / O) including power (PWR) and ground (GRD). Each I / O ring is programmable to be either analogue or digital. The rings are suitable for crocodile clips or 4 mm banana plugs, meaning an external sensor can be connected to measure things like temperature, humidity, proximity to other devices. The micro: bit reads values from the sensor and acts on them or sends them to another device. The micro: bit can also send control commands to the rings - these could be used to control things like a motor or robot. The PWR and GRD rings supply 3 volts and could be used to power a separate device.
Edge connector: 20 pins, 1.27 mm pitch and extend 7.62 mm from board edge suitable for standard connectors. This allows the micro: bit to be connected to another device, eg Arduino, Galileo, Kano and Raspberry Pi through a standard connector.
Micro-USB controller: This is controlled by a separate processor and presents the micro: bit to a computer as a memory stick. This means the program can be dragged onto the micro: bit in the same way a file is dragged onto a memory stick.
