Overview
About BBC micro:bit V2.
The BBC micro:bit V2 is an education-focused microcontroller board designed to make coding and physical computing approachable for students and beginners. It is built around the Nordic nRF52833, a 64MHz Arm Cortex-M4 with floating-point unit, and adds a wealth of onboard hardware so you can build interactive projects with no extra components.
Onboard it packs a 5x5 red LED display, two programmable buttons, an accelerometer and magnetometer (compass), a temperature sensor, a MEMS microphone with sound sensing, a built-in speaker, a touch-sensitive gold logo, and 2.4GHz radio plus Bluetooth 5.0 for wireless. The 25-pin edge connector lets you attach crocodile clips, banana plugs or accessory boards, and it is programmable via the beginner-friendly MakeCode block editor or Python.
For India buyers, the micro:bit V2 is the standout choice for schools, coding clubs, STEM kits and first-time makers. Its all-in-one sensor suite means students can build meaningful projects on day one, and its browser-based MakeCode editor needs no complex software setup, making classroom rollout simple.

Buying guide
How to choose.
Choose the micro:bit V2 for education, coding clubs and beginners who want an all-in-one board with sensors, a display and sound built in. Its V2 upgrades (microphone, speaker, touch logo, faster Cortex-M4) enable audio and machine-learning-style projects the V1 could not do; buy V2 rather than V1 for any new deployment.
For classrooms, look for the micro:bit V2 'Go' kit, which bundles a battery holder, two AAA batteries and a USB cable so students can start immediately. To build larger projects, pair it with the many available accessory boards (motor drivers, breakout boards, robot chassis) that connect to the edge connector.
It is programmed for free in the browser using Microsoft MakeCode blocks or Python, so no software install is needed. Pair it with a USB cable for coding, a battery pack for portable projects, and crocodile-clip leads for quick sensor and actuator experiments.
FAQ
Common questions.
How do I program the micro:bit V2?
Use the free browser-based Microsoft MakeCode block editor or the Python editor. Write your code, download the .hex file and drag it onto the micro:bit, which appears as a USB drive. No software installation is required.
What is new in V2 compared with V1?
V2 adds a built-in microphone and speaker, a touch-sensitive logo, more memory and a faster Cortex-M4 processor, plus a power-saving mode. These enable sound-based and lightweight machine-learning projects the V1 cannot run.
Does it need extra components to start?
No. The 5x5 LED display, buttons, sensors, microphone and speaker are all onboard, so students can build many projects with just the board and a USB cable or battery pack.
Is it Bluetooth compatible with phones?
Yes. The V2 supports Bluetooth 5.0 (BLE), so you can pair it with a phone or tablet for wireless control and data, and it can also talk to other micro:bits over its 2.4GHz radio.
Is it available in India and what is the Go kit?
Yes, the micro:bit V2 is widely available in India. The 'Go' bundle adds a battery holder, batteries and a USB cable, making it the easiest option for schools and beginners.
What comes in the box?
The bare board comes on its own; the micro:bit V2 Go kit includes the board plus a battery holder, two AAA batteries and a micro-USB cable.
