You can programming, customize or control it as well.BBC micro:bit version 2.2 is better than ever! Maintaining the same size and compatibility as the previous v1 version, the micro:bit is now equipped with Bluetooth 5.0, 4 times more processing power, and 8 times more memory than the original micro:bit. With the increased memory, it is now possible to program in MicroPython with greater freedom, which was previously limited by memory issues. In addition to more processing power and memory, you can now talk to your micro:bit thanks to the mic and speakers already built into the board. Another detail is the now touch-sensitive logo, allowing multiple points of interaction with the micro:bit.In addition, the 2nd generation Micro:bit board also support sleep mode.
