If a GPS module is installed on the 100-pin connector, the pins for expansion port 3 are passed
through to a 22-pin connector on the back of the module (see Section 6.2: “Connector Locations”).
This connector is identical in form and pinout to expansion port 2 as described in Section 6.4.3:
“Expansion Port 2 (Pod Expansion Connector)” – use those specifications instead when using
this connector.
The following pinout table only shows the pins for the expansion port 3 interface of the 100-pin
connector. For descriptions of the remaining pins and interfaces, see Section 6.5 on page 102.
