The connector is mounted on the top side of the board with longer tails to allow insertion
into the BeagleBone Black.
Figure 60
is the connector configuration for the connector.

Stacked Cape Expansion Connector
For convenience listed in
Table 18
are some possible choices for part numbers on this
connector. They have varying pin lengths and some may be more suitable than others for
your use. It should be noted, that the longer the pin and the further it is inserted into the
BeagleBone Black connector, the harder it will be to remove due to the tension on 92
pins. This can be minimized by using shorter pins. There are most likely other suppliers
out there that will work for this connector as well. If anyone finds other suppliers of
compatible connectors that work, let us know and they will be added to this document.
The first item in
Table 13
is on the edge and may not be the best solution. Overhang is
the amount of the pin that goes past the contact point of the connector on the BeagleBone
Black.
The third part listed in
Table 17
will have insertion force issues.

There are also different plating options on each of the connectors above. Gold plating on
the contacts is the minimum requirement. If you choose to use a different part number for
plating or availability purposes, make sure you do not select the “LT” option.
Other possible sources are Sullins and Samtec but make sure you select one that has the
correct mating depth.

Stacked Capes w/Signal Stealing
Figure 61
is the connector configuration for stackable capes that does not provide all of
the signals upwards for use by other boards. This is useful if there is an expectation that
other boards could interfere with the operation of your board by exposing those signals
for expansion. This configuration consists of a combination of the stacking and non-
stacking style connectors.
