Yes, the Pi 5 still supplies power to the 3.3V rail after a clean shutdown. To fully cut power, you'd need an external circuit or smart power management HAT that shuts off power completely after shutdown.I got a Pi5 that I'm going to use as a small NAS. I got all working except the poweroff behavior.
I have connected a LED to the 3v3 header pins and I have noticed that if I do a hard poweroff holding the power button it turns off but if I do a clean shutdown with a single button press or using poweroff/shutdown commands it stays lit, so I assume the pi is still powered.
Is it possible to perform a full power down with a proper clean shutdown?
