About the BBC micro:bit –

The Micro Bit (also referred to as BBC Micro Bit, stylised as micro:bit) is an ARM-based embedded system designed by the BBC for use in computer education in the UK. The board is 4 cm × 5 cm and has an ARM Cortex-M0 processor, accelerometer and magnetometer sensors, Bluetooth and USB connectivity, a display consisting of 25 LEDs, two programmable buttons, and can be powered by either USB or an external battery pack. The device inputs and outputs are through five ring connectors that are part of the 23-pin edge connector at the bottom of the board. The micro:bit can be programmed using the Microsoft Block code program editor which is similar to the block based language Scratch ideal for 7-12 year olds. The micro:bit can also be programmed using the Makecode editor in Javascript and Python which allows for older kids to learn the Javascript and Python programming language using the micro:bit.

You can read more about the BBC micro:bit at the microbit website. Also see Kitronik’s resources here – Parents Complete Guide To The BBC micro:bit.
