BBC Micro:bit Development Board

Half the size of a credit card and simple in design, the BBC micro:bit board is offering school teachers a new way of introducing their pupils to the joys of electronics programming.

It is equipped with an ARM processor, numerous  pin and I/O ports, colour LEDs, a set of sensors (magnetometer, accelerometer, temperature sensor, etc.), and various programmable buttons. You can connect the micro:bit to a mobile phone using a micro-USB socket. With its Bluetooth Low Energy antenna, it can interact with other devices or connect you to the internet.
