The BBC micro:bit v2 is a pocket-sized programmable computer designed for creative digital projects and coding education. Powered by a 64MHz ARM Cortex-M4 processor with FPU, 512KB flash, and 128KB RAM, it packs an impressive array of sensors and outputs into a board half the size of a credit card.
Program it using MakeCode (block/JavaScript), Python, or Scratch, and send code wirelessly via the micro:bit mobile app over Bluetooth 5.0. The v2 adds a built-in speaker, MEMS microphone, and capacitive touch logo to the feature set.

Jargon buster
Plain-language definitions for the technical terms used above.
- ARM Cortex-M4
-
The ARM Cortex-M4 is a 32-bit processor core widely used inside microcontrollers, often with hardware support for signal-processing and control tasks. It provides enough processing power to run embedded programs that handle sensors, wireless communication, audio and similar workloads.
- BLE
-
BLE stands for Bluetooth Low Energy, a Bluetooth mode designed for low power use and broad compatibility with modern phones and computers. It connects well to battery-powered and mobile devices, including Apple hardware, though it behaves differently from Bluetooth Classic and its serial-style profiles.
- FPU
-
A floating-point unit is hardware inside a processor that speeds up calculations with decimal numbers. This helps when projects use maths-heavy tasks such as motion sensing, filtering sensor readings, or audio processing.
- LED
-
A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- MEMS microphone
-
A tiny microphone made using micro-electromechanical systems, the same style of miniature manufacturing used in many phone sensors. It lets the board detect sound without needing an external microphone, which is useful for noise-reactive projects and simple audio input.
- Motion detection
-
The ability to sense that something has moved, either by comparing successive camera frames or by using a dedicated sensor such as a PIR (infrared) or radar module. When a product lists motion detection, movement can be used as a trigger so a system only acts or records when there is activity rather than running continuously.
- RAM
-
RAM (random-access memory) is fast, temporary memory a device uses for working data while it is running; in its common volatile form, its contents are lost when power is removed. Some devices offer a mode that applies settings to RAM only, which is handy for testing changes temporarily because they are not stored permanently and disappear at power-off.
