I am a bit confused by the relay that you linked to. It has conflicting information: on the page it mentions it’s 24VDC, but then the image and title both say coil voltage is 12VAC. I think if you can find 12VDC latching relay it should work just fine — OSBee switches on or off a latching relay by sending an impulse voltage, which lasts only a brief moment, so the specific voltage doesn’t really matter very much.

You can also use a standard DC non-latching relay — in that case you need to set the controller in non-latching mode and short the non-latching solder jumper. That way, the 5V from USB will provide continuous current to keep the relay on. The reason to use this is that non-latching DC relays are much more common and cheap to buy.
