Hello, does anybody Know if I can use a 4.5v dc power source with this module? I want to connect it to an object which is battery powered 4.5v. If not do you know how I could convert the 12v to 4.5 after the 12v DC adapter and module connection. Any technical advise/help is hugely appreciated. Thanks!
Sorry, this module needs 12V to operate, it will not operate from 4.5V
The output however, is a relay contact, so you can use it with any voltage you like (which is within specs).
