microbit V1 and micro:bit V2 comparison main

There is a new micro:bit in town and we couldn't be more excited! We head to the workbench to compare the differences between micro:bit V1 and microbit V2. We take a look at both the features and also the technical specifications. 

The original microbit has so much going for it in terms of features --that you will now be able to do more with it makes it an exciting proposition for the classroom. Let's find out more;

 

The User Features of micro:bit V1 and micro:bit V2:

The good news is that all of the original micro:bit features are also present in version 2. Additionally, the blocks in the MakeCode editor for the old features are exactly the same. Any learning curve that V2 has is only about the new features.

The table below lists all of the features for both boards for much easier comparison, new or improved features are highlighted in green. Check it out.

It's important to also point out that the board also features a number of usability enhancements, they are;

  • Notched edge connector. To make it easier to connect things like crocodile clips and also conductive thread.
  • Power LED indicator. In addition to the USB activity indicator.
  • Gold plated antenna. To easily identify the radio and Bluetooth component.

The new micro:bit speaker works the same as it does when you currently connect a speaker to the micro:bit and the sound output will be on both the speaker and the edge connector. The new microphone blocks in the MakeCode editor will allow you to write code that reacts to sound.

 

The Tech' Spec's of micro:bit V1 and microbit V2:

Much of the onboard tech has also been enhanced. The processor and memory has been upgraded which has also allowed upgrades to other on-board technologies.

Kitronik Accessory Boards For micro:bit Compatibility::

The microbit V2 is the same physical size and also has the same edge connector configuration as the original That means many of our micro:bit accessory boards will work fine with V2. We are in the process of thoroughly testing all of our micro:bit accessory boards and when complete, we will publish the list here.

 

Coding and MakeCode Compatibility:

To ensure the greatest degree of continuity for teachers, users will not need to select which version of the device they have before using MakeCode or the Python Editor. Instead, the editors will support a new format called “universal hex” which can run on both micro:bit V1 and micro:bit V2 (more below). New MakeCode blocks have been added to the editor for the touch logo and microphone, these can be found in the Input section.

This means that you can use MakeCode or the online Python Editor as you always have, to use all of the features that are common to both version of the BBC micro:bit: Display, buttons, motion sensing, gestures like shake, light sensing, and even the Music blocks.

Every program that could run on a micro:bit version 1 can be re-built to run on microbit V2. The editors will support both versions simultaneously for features common to both boards. To convert an old HEX file into a universal HEX file, drag it into the editor it was created in and then export it back to your computer where it can be dragged and dropped onto the micro:bit. If you attempt to use an old .Hex file without updating it, the micro:bit will display a compatibility error.

 

Conclusion:

We think you'll agree that this is quite the upgrade, in terms of both features and technical spec's. As well as all of the new features, there are a ton of enhancements to existing features. That's without mentioning the upgrade to many of the underlying technologies. Despite all of these changes, you code the new microbit and use it in exactly the same way. Which means you don't have to learn it all over again, just get to grips with the new features and you are good to go.

If you are juggling a school budget, not having to also source speaker and microphone solutions will free up valuable cash/time resources for other things.
