Gaze lovingly at its square modern shape \u0026amp; its glossy clear cover!\u003c\/p\u003e\n\u003cp\u003eUsing this case is very easy and works with Beagle Bone Black (not for original BB!) Snap the BBB into the case bottom for a secure press fit. If you want to poke around you can leave the top cover off. If you want to protect your Bone, fit the cover on, it will fit securely so you can put the Bone into your bookbag or briefcase without worry. All cables can be plugged in, we even made a little divot so you can pop the optional microSD card in and out.\u003c\/p\u003e\n\u003cp\u003eThe way we designed the top\/bottom split, the bottom half is right at the female expansion header's height. That means you can remove the clear top and place shields on top, even ones that are larger than the BBB itself, and the bottom will provide protection and clearance\u003c\/p\u003e\n\u003cp\u003eSome MicroHDMI cables have rubber mouldings that are a little long and interfere with the MicroHDMI slot seating well.
