MI：pro是micro：bit的簡單而有效的保護套。 具有三層構造風格，可以將整個組件掛裝到任何需要的表面上，同時還可以連接micro：bit上的所有按鈕和端口。 雖然都具有壁掛式標籤，但使用外殼的最大好處是不容易刮傷micro：的背面。
Construction is simple, requiring only a small flathead screwdriver, and involves layering each plate on top of one another around the micro:bit and screwing it into place. Luckily, the MI:pro case enables easy access to the edge pins at the bottom of the micro:bit, allowing it to still be plugged into an edge connector found on many of our carrier boards. The only board that cannot be used in conjunction with the MI:pro case is the SparkFun gamer:bit due to its edge connector being located in the center of the board.
Note: The MI:pro case only includes the parts found below. This case does NOT include a micro:bit, power source or mounting screws. These items will need to be purchased separately.
