Connecting the power supply to the nanode:
In this image, the white wire is power, and the black wire is GND. When placing the barrel jack with the three pins facing down, the center/bottom pin is GND and the right side pin is POWER.
Now connect the wires to the Nanode using two screw terminals. Make sure yours is setup identically to this one!
When you plug the power supply in, you should see the red power indicator on the Nanode light up! If it doesn’t, immediately disconnect and check out your setup once more.
