The Micro Bit (also referred to as BBC Micro Bit, stylized as micro:bit) is an open source hardware ARM-based embedded system designed by the BBC for use in computer education in the UK. Its popular has been growing due to the wide adaptation of product given its simple block-based programming environment.
The device is described as half the size of a credit card 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 form part of a larger 25-pin edge connector. The five connectors comprise of three for digital/analog I/O and two for power and ground for hooking up external components. The tabs with larger holes can be easily used with alligator clips to prototype added components quickly.
Important: The micro:bit does not include any cables or power sources. This is just the board. We recommend picking up a micro USB cable to power your board.
