Doorbell setup with nicor chime

Because there are so many models of chime, I have to say just ensure the voltage output matches the input requirements. I carefully stated the make and model I used because of all the confusion out there.

No one mentioned 5V. The VDB runs off 16V-24V AC if you are using the screw terminals, but 5VDC USB power if you peel off the gray rubber on the back and expose the USB connector. Caution: Make sure it is still waterproof, as that gray rubber was a waterproof seal to protect the production test port.
