BBC Micro:bit V2.2 for classroom coding

The Micro:bit V2.2 is a pocket-sized programmable computer built for teaching coding and digital making in schools and clubs. It adds an onboard speaker and microphone so students can create sound-based projects without extra hardware. Twenty-five individually addressable LEDs and two programmable buttons give immediate visual and tactile feedback.

Beginners who want instant results without soldering

This board suits teachers, students and hobbyists who need a ready-to-program platform with built-in sensors for light, temperature and motion. Buyers who require more processing power, additional GPIO pins or a Linux environment should look at other single-board computers.

Version 2.2 adds speaker and microphone

The V2.2 revision integrates a MEMS microphone and a piezoelectric speaker directly on the board, enabling sound input and output for interactive lessons. Earlier revisions lack these audio features, so confirm the version before purchasing for sound-dependent projects.
