Single Cape Expansion Connector
It is allowed to only populate the pins you need. As this is a non-stacking configuration,
there is no need for all headers to be populated. This can also reduce the overall cost of
the cape. This decision is up to the cape designer.
For convenience listed in
Table 16
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 or removing those pins that are not
used by your particular design. The first item in
Table 16
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 G in the part number is a plating option. Other options may be used as well as long
as the contact area is gold. Other possible sources are Sullins and Samtec for these
connectors. You will need to insure the depth into the connector is sufficient

Main Expansion Headers-Stacking
For stacking configuration, the two 46 pin expansion headers use the same connectors.
Figure 59
is a picture of the connector. These are dual row 23 position 2.54mm x
2.54mm connectors.
