2.1 Dimensions and Layout

The overall dimensions of the Iridium 9523 and its weight are summarized in Table 2 and represented
graphically in Figure 2.
Height (from FA board)
Weight (approximate)
The Iridium 9523 consists of a single PCB with components mounted on top and bottom sides.
On the top side, there are three reservoir capacitors, the RF connector, and a screening can covering all
the remaining circuits.
The bottom side has a Molex 40-pin multi-way user interface connector. The bottom side does not have a
screening can, but instead the PCB artwork has an exposed ground ring all around the edge of the board.
This ground ring makes contact with an aluminum screening frame, attached to the Iridium 9523 by four
corner thread-forming screws. The tips of these screws protrude through the aluminum frame and act as
alignment pins when mounting onto the FA board. The aluminum frame also has at its center a 1.0mm
diameter alignment pin.
There are a further four corner screw holes through the aluminum frame and PCB for securing the 9523
to the FA board.
The two height values provided in Table 2 do not include the height of the compressible gasket on the
bottom of the 9523 that will mate to the FA board. It is assumed that this gasket will compress to near
zero thickness if screws are torqued sufficiently.
