Fun IoT capabilities
Using the radio feature to communicate between two micro:bits was my first project. It worked flawlessly out of the box. The only reason for 4 stars is the LED matrix resolution is low, but that's expected.

Perfect for classroom coding lessons
We bought a set of these for our middle school computer science club. The v2.2 upgrade with the built-in microphone is a game changer for sound-based projects. Setup was incredibly easy using the online editor.

Solid board, wish batteries were included
The board itself is fantastic and very durable. My only minor complaint is that the battery pack isn't included in this specific kit, so you need to buy it separately if you want portable projects.

Easy transition from Blocks to Python
I started with the block-based editor and moving to Python text coding was seamless. The documentation is excellent, and there are thousands of tutorials available online for inspiration.

Industry standard for education
We use these across all our workshops. The Bluetooth connectivity allows for wireless data logging which is perfect for science experiments. Robust construction handles drops well.

Great upgrade from v1.5
The faster processor and larger memory make a noticeable difference when running complex Python scripts. The speaker quality is surprisingly good for such a small board. Highly recommended for hobbyists.
Q: Does this work with the MakeCode editor offline?
A: While MakeCode is primarily web-based, you can install the Microsoft MakeCode app for Windows, macOS, and ChromeOS to program the device offline.
Q: Can this board be powered directly via USB-C without batteries?
A: Yes, the micro:bit v2.2 can be powered directly through the USB-C port when connected to a computer or a standard USB power adapter.
Q: Can I use this with Thonny IDE for Python development?
A: Yes, Thonny IDE supports the micro:bit v2. You will need to install the appropriate micro:bit plugin and ensure your firmware is up to date.
Q: What is the maximum current draw per GPIO pin?
A: Each GPIO pin can source or sink up to 5mA safely. For higher current requirements, we recommend using an external transistor or driver circuit.
Q: Is the microphone sensitive enough for voice activation projects?
A: Absolutely. The v2.2 features a built-in MEMS microphone that is sensitive enough for clap detection, voice level monitoring, and simple voice-activated triggers.
