Custom Power Rail PCB - Is this shematic OK?

I'm going to make my self an power rail for my desktop in workshop for powering 5V devices as Arduino Nano and som other Breadboard projects that needs 5V.

I'm going to use an N-channel mosfet and an Attiny for this (i think).

Can someone take a look at the chematic under and give me som feedback please?

What's the intended purpose of the FET?

Switching Gnd is not recommended, better use a P-channel high side switch.

I want to use Attiny85 to switch the output power ON/OFF.

I second and agree with what DrDiettrich said.
Plus I cant see the point in this why not just use a switch instead ?

Because all that's doing is just turning on all the outputs same time why over complicate things with a micro. May be I could see some use if the outputs where individually controlled but then again you'd still have to press a button to turn it on and off so again I'd still just use a switch

You want to turn off the output? Why not turn off the unidentified 12V source?

Maybe i have overthinked this as you said.

I just wanted to control the mosfet and Attiny85 was the first that came up. Maybe a switch is the simplest after all...

Thanks :slight_smile:
