  • If using this with a standard center-positive 5.5x2.1mm barrel connector: The leg in the center of the plastic body is the positive lead, while the other two (on the outer edges of the plastic body) are both connected to one another and are the negative leads.

  • For those of you trying to figure out how to wire this thing, you can see that on one side there is a second smaller leg with a small hole in it. This is the anode (+) lead. The other side with a single leg and no tiny hole is the cathode (-) lead.

No public wish lists :(
