MI:pro Protector Case for micro:bit

The MI:pro Protector is a simple and compact protective case for the micro:bit. These cases feature a four-layer construction style with ability to mount a 2xAAA battery pack to the back of the case while still providing access to all buttons and ports on the micro:bit. Though these cases do protect the micro:bit astoundingly well, the biggest benefit of using the MI:pro is to not accidentally short out the pads on the back of the micro:bit.

Construction is simple, requiring only a small flathead screwdriver (at most), and involves layering each plate on top of one another around the micro:bit and screwing it into place. Luckily, the MI:pro Protector 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 Protector case only includes the parts found in the Includes Tab. This case does NOT include a micro:bit, power source or mounting screws. These items will need to be purchased separately.

    And the kit say to use the metal screw and one of those nuts to hold the battery holder, or cage in place. I used the one from the SIK for the device temporarily. (This was this one, https://www.sparkfun.com/products/retired/14542 , which I bought from the same place where I bought a BIT device from, Micro Center.) It seems that the screws would work with this style holder if they were placed on the same piece where the holder is mounted. Is the battery holder sold through Sparkfun the same style that they want used, the holder maker, or is it a different style, since this holder isn't switched.

      I am not quite sure I understood your question, but I'll do my best to answer:

    Minor problem: the kit says to use the metal screw to attach the battery holder (they call it a "cage" or "pack") using the metal screw and one of the nylon nuts. Only problem is that the battery holder included in the micro:bit Go Bundle doesn't have a pre-drilled hole. I'll probably just use a small piece of double-stick tape in lieu of the screw.

    I'm not really complaining, but think that others should be made aware of it before they (or their grandkids) get really frustrated.
