Ciao jhornbr225 yes i can confirm that my relay module has already got a transistor and a resistor. The module is a " KY-019" relay (this https://www.amazon.it/gp/product/B07BVXT...ge?ie=UTF8&psc=1 the italian link) that could be triggered using the 3.3 v. The power will not come from raspberry, only the trigger signal will come from raspberry (i've used the same in another raspberry project to switch on a vacuum cleaner vent)
