This handy USB extension cable will make it easy for you to enclose a device that has a A type (USB host) port. We think this would be most handy when putting a Beagle Bone, Raspberry Pi or Mintyboost into a box.

The jack half has two mounting 'ears' with 4-40 screws installed, 30mm apart. The ears are flexible so the holes don't have to drilled very precisely. Can be used with box walls up to 0.25" wide. The screws can be put on from the back for 'reverse' mounting if the box thickness is a problem. Entire unit is 13.4" long from tip to tip (with 10.2" cabling between USB connectors).
