The Universal Connector was a standard port fitted to the bottom of many Palm PDA's from 2001 to 2004 and on units from other manufacturers that licensed Palm technology, including Garmin.

Out of the box, it is used to connect to the sync and charge cradle, allowing the Palm to connect to a desktop PC and receive battery power. A range of accessories were also available for the Universal Connector, including folding keyboards, external battery packs, wired and wireless modems, and many more.

The Universal Connector cradles were the first synchronization device that used USB to communicate with the host computer, in addition to the older serial port standard.

Some Palm devices manufactured between 2001 and 2004 did not use the Universal Connector. For instance, the Tungsten E had a mini-USB connector.

The Universal Connector has now been abandoned in favour of a newer standard, the Palm Multi-Connector.
