Tiny board, massive features! Discover every component, sensor, and connectivity option that makes the Micro:bit an amazing learning tool.
Meet the essential parts of your Micro:bit board!
25 individually programmable red LEDs arranged in a grid. Display text, numbers, icons, and animations! Each LED can be turned on/off or set to different brightness levels.
Heart pattern example
Two user buttons – A and B – that you can program to do anything! Press, double-press, or combine them (A+B) for different actions.
Connect motors, sensors, speakers, and other accessories using the gold edge connector pins. Pins 0, 1, 2, 3V, and GND are the big ones — perfect for crocodile clips!
Main accessible pins
Your Micro:bit is packed with sensors — no extra wires needed!
Detects movement, shaking, and tilting in 3 axes (X, Y, Z). Build motion-controlled games, step counters, and tilt-activated alarms!
Find North and measure magnetic field strength! Build a digital compass, treasure hunts, or navigation tools for your outdoor adventures.
Measures the temperature of the processor chip (close to room temperature). Build weather stations and temperature alerts!
The LED matrix doubles as a light sensor! Measure ambient brightness and create projects that respond to light and darkness.
The Micro:bit V2 comes with amazing new features!
Detect sounds, measure noise levels, and create voice-activated projects! The on-board MEMS microphone opens up a whole world of audio-responsive ideas.
Play melodies, sound effects, and speech without any extra hardware! The edge-mounted speaker makes it easy to add audio to any project instantly.
The golden Micro:bit logo on V2 is a capacitive touch sensor! Use it as a third button for even more interactive project possibilities.
Connect, communicate, and collaborate wirelessly!
Connect your Micro:bit to smartphones, tablets, and other Bluetooth-enabled devices. Control your Micro:bit from a phone app or send data wirelessly!
Let multiple Micro:bits talk to each other! Radio messaging is super simple and perfect for multiplayer games, walkie-talkies, and group activities.
