No, at this point the ioStack beta units do not have an enclosure so ioStack users should plan accordingly. The ioStack will need to be installed in a location that is protected from moisture and other possibilities of physical damage.
ioStack should be handled with care as touching the circuity and chips could result in a static discharge that damages the device. It is best to be grounded when handling circuit boards and/or pick up the board from its edges to minimize contact with its circuitry and chips. More on how to safely handle circuit boards can be found here.
