I need to dock the 12V relay when giving the command via software, however, the GPIO provides only 3.3V not being enough to arm the relay.
My idea is to use a voltage booster (Step-up Mt3608) to raise the 3.3V to 12V and arm the relay.
I am using a dry contact relay, so the 12V would only be used to arm the relay and will not feed or share voltage with any other device.
Could this cause any harm to Raspberry or GPIO?
