Additions on the Microbit V2

The Microbit V2 has come up with certain additions to it, that Microbit V1.5 lacked.

  1. The Microbit V2 has an additional  Microphone input and an LED indicator that shows the Microphone is on.
  2. As there is a Microphone Input there is also a Speaker that comes with the Microbit V2.
  3. The Microbit logo on the V2 is now touch-sensitive ie. it now acts as an additional input along with the two buttons ‘A’ and ‘B’ that were the only physical inputs in Microbit V1.5.
  4. With 3 GPIO pins already in Microbit V 1.5, the V2 has an additional GPIO making it 4 GPIO.
  5.  The Microbit V2 has an enhanced processor on board along with increased Flash and RAM capacity.
  6. The current availability for accessories is also increased from 90mA to 200mA.
  7. The Interface chip is more advanced and has more RAM capacity than the one used in Microbit V1.5

Choosing a Microbit for your application

After specifying the Differences and new additions to Microbit v2, it is fairly clear

  1. You should prefer the Microbit V2 if you need to have a microphone and speaker configuration in your project.
  2. If the Code that you are uploading is big and might only get bigger, go for the Microbit V2, as it has better interface capabilities.
  3. If you need additional input on the board in form of touch apart from the two buttons, you can choose the Microbit V2.
  4. As the cost difference is not significant when compared to the additional features that come up with the Microbit V2, there is no turning back from buying the V2.
