Hi, I'm new to Arduino and I have a Nano 33 IoT I'd like to use to switch on a Raspberry Pi 4 B. As I understand it, since the Nano 33 outputs 3.3V and the Pi takes 5V, controlling power directly is a no-go. Both devices will be powered via wall outlet, so absolute minimization of power consumption…

Controlling external power via relay with Nano 33 IoT

why not just use a WiFi controlled mains socket?
