Beginners Note: Inside the jack (pin on the gumstix, or inside on the power adapter) is +5V. Higher voltages run greater risks of destroying your gumstix. Outside, or on the edge, is ground.

Robostix/Roboaudiostix Note: Normally power can be applied to any daughtercard, but when using a robostix that board must be powered. See Robostix Voltages.

The power jack is part of the connection between the batteries and the voltage regulators. See power spec and robostix power for more details.
