It is the new standard to replace the previous Palm Universal Connector, which performed similar functions but did not have an audio output capability.

This port has also been used to connect to an external microphone or to GPS units The connector is divided in two sections: the longer one has thirteen pins numbered from right to left (5 to 17); the shorter one has three pins, on the left (3), top (2) and right (1).

The cable shield connectors (4,18) are located on each side of the thirteen pins.

Users have been frustrated with the requirement to replace their Universal Connector cables, cradles, keyboards, sleds, and attachments as they have become incompatible.

Another criticism is that the connector is fiddly, harder to remove and feels fragile.
