DC power jack/connector. This is a common barrel-type power jack for DC wall supplies. These are compatible with our DC wall supplies and have a 5.5mm jack, with a 2.1mm center pole diameter.
If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

The ground contactor is not connecting with the barrel on the unit I purchased. I hope it’s just a fluke, so I’m buying another one. I’ve tried pushing the tab back and forth and up and down with no luck.
It also would be nicer if these were regular through-hole pins instead of the tabs. The layout for this part on sparkfun’s eagle library just has round holes that these tabs don’t fit through.
