The BBC micro:bit Single contains 1x BBC micro:bit V2 board
The BBC micro:bit is a pocket-sized computer that introduces you to how software and hardware work together. It has an LED light display, buttons, sensors, a speaker, microphone and many other input/output features that, when programmed, let it interact with you and your world.
Please note you will also need a battery back with 2x AAA batteries (not included in the Single pack) as well as a USB lead to connect your micro:bit to a computer. (If you send code to the micro:bit from a tablet or phone via Bluetooth, rather than using a computer, then the USB lead is not necessary).
