BPI-P2 Zero overall height

Could anyone supply me with the overall height of the P2 Zero? I haven’t received mine yet, but I would like to know how long of board stand offs I would need to stack a board on top of the main board.

Thanks in advance!!

unfortunately that does not contain the height of the device, only length and width.
