    Description
    Note: From April 2022 onwards, micro:bit Junior kit now comes with a micro:bit V2 board and a USB micro B cable.
     
     
     
     
     

     

    The Junior Kit for micro:bit, NOW with V2!

    This microbit Junior kit is a basic kit to kickstart digital making. Perfect for primary and secondary school students to learn coding, microcontroller, LED, sensor and motor.

     

    Do check out the review of micro:bit V2 vs V1.5 by young maker, Jayden Lam:

     

    micro:bit - The Microcontroller for Everyone

    Well, as the name says, this is the enhanced version of the micro:bit controller.

     

     

    micro:bit V2 vs micro:bit V1.5

    micro:bit is a tiny microcontroller board with a powerful ecosystem, and it is being built by the BBC. This BBC micro:bit is a pocket-sized computer that lets you get creative with digital technology. You can code, customize, and control your micro:bit from anywhere! You can use your micro:bit for all sorts of unique creations, from robots to musical instruments and more.

     

    Easy To Use, Free Graphical Programming Environment

    makecode.org

    Combine with graphical programming from an online editor: makecode.org, you can get started in less than 5 minutes! You can already start with the 5x5 LED matrix on the micro:bit board as a good visual output, displaying simple graphics or animation. Not to forget the two push buttons A and B as digital inputs and a built-in accelerometer for vibration and orientation detection. And with the V2, there is an additional microphone (sound detector) and speaker (buzzer) on board, there are tons of emoticons and example codes in MakeCode Editor at your disposal. Students will enjoy learning art, music, and coding, all at the same time.

     

    At half the size of a credit card, you will be surprised at the amount of hardware each board is equipped with, including 25 red LED lights that can flash messages. There are two programmable buttons that can be used to control games or pause and skip songs on a playlist. The micro:bit can even detect motion and tell you which direction you’re heading. It can also use Bluetooth Low Energy (BLE) to interact with other devices and the Internet.


    Taking a closer look at the front of the V2 board, we can see the 5x5 LED array is still there for you to draw on, display words, numbers, and other information, and of course the two programmable cute buttons!

    V2 board comes with a MEMS microphone input hole and a mic indicator LED. If the sound input is enabled in the program or your code, the mic indicator will be illuminated. And not to forget the micro:bit logo, it is now a capacitive touch sensor. If you look carefully, it is now gold plated PCB instead of the color mask on the previous version board :) So it can be used to detect touch. Awesome improvement!

     

    On the back of the board, you will find the upgraded brains of the micro:bit. The microcontroller on the micro:bit V2 has been upgraded to nRF52833 with double the memory size to 512KB Flash, and 8 times larger size of RAM to 128KB.  With the upgrades of the main controller, micro:bit V2 is now Bluetooth 5.1 and also BLE (Bluetooth Low Energy).

    Besides the MCU, the co-microcontroller that handles USB connection, KL26Z with 16KB RAM is being upgraded to KL27Z with 32KB of RAM too. micro:bit V2 still comes with an accelerometer, compass, and Bluetooth Smart antenna, as well as a micro USB and two-pin JST connector for different power options.

    Finally, at the bottom of the board, you will still get the 20 gold-tabbed edge pins and however, the five ring connectors (three for digital/analog I/O, two for power and ground) for hooking up external components now come with notched edges. These notched edges will help the insert into the socket. And you can always use the crocodile/alligator clip :)



    Of course, the intuitive mobile app that lets you send your code to your micro:bit over Bluetooth (without using a USB cable) and more remains compatible with the new micro:bit V2. With this app, you will be able to interact with your micro:bit on a higher level of accessibility.

     

    This kit comes with a special box too. The box can be utilized not just to keep the micro:bit and USB cable, but also as a project box. The micro:bit can be mounted from inside of the box cover, exposing the LED matrix and push buttons, while protecting the other parts of PCB.

    You can still program and power the micro:bit while it is attached underneath the cover as the box is creatively being designed to allow access of the USB cable from the back:

    The box is not only for keeping parts, but it is also part of projects :) There is plenty of space in there for many more components, so use it!

    In the case where you need it to be portable, we would recommend you to get this AAA battery holder with a switch and terminate with a JST connector that matches the micro:bit.

    Not forget the AAA batteries that you need:

    Q & A (2)
    if i buy microbit junior, do i still need to add 2xAAA Battery Holder with On/Off Switch? ( Abby, 09/12/2021 )
    Hi. Depends if you need to use the microbit with battery then you can option to purchase the battery holder too :)
    What is different between microbit junior (RM49) and microbit board (RM72)? ( Zul, 18/12/2019 )
    Hi, they are the same is just that the Microbit Junior Kit comes with USB Cable. Thanks :)
