GPIO output volatge 5v or 3.3v?

Hi, sorry I am quite new in working with jetson nano. So what do I want to do to controll relay with Jetson via GPIO. Relay requires 5v controlling pin, so it is quite simple to control with oython GPIO library, sending 1 to control pin is switching the relay.

However, the problev that the relay demands 5v controlling voltage, and I don’t know which voltage output is from GPIO. And if it is 3.3, is it possible to change it for 5v.

Thanky you in advance

The logic signals at the 40 pin header are all 3.3v. You’d need to supply your own level shifter if your 5v relay won’t accept 3.3v.
