Or sos-solutions and audiophonics is also an option. Plenty of choice. I’d rather order things from within the country. Or at least from a store that doesn’t sell worldwide.

I am still not to sure how to power of the raspberry pi. The Pi will be powered by a linear power supply. The dac, it’s going to be a Khadas tone board which is on it’s way, wil also be powered by the same power supply, or thru ether raspberry pi.
I know the pomorino on off shim can do this but it needs to sit on the pi itself.

And there’s the power management module from audiophonics

https://www.audiophonics.fr/en/power-supply-modules/audiophonics-pi-spc-reg-power-management-power-supply-for-raspberry-pi-p-11504.html

But that needs a 7 to 12 volt power supply. Mine is 5v.

What other solutions are there to completely power down the pi, with volumio on it?

not a great option, only used if you only want to power the pi without a screen

@michel8166 maybe you could advice him how to power his setup.
( you have created already many of these setup’s with a simulair dac )

Silly question maybe but what is the difference between power off the pi with or without a screen? The screen, in my case a 7.9 inch waveshare, gets its power from the pi. So how I see it, when you power off the pi the screen is also powered off or doesn’t it works this way?

your shim only can deliver 2.5 amps a basic pi4 with a screen draws 3 amps so you will be short of 0.5 amps resulting in strange behaviour and you don’t know why… it’s because the shim can only power the pi
and has not enough power to power the screen / dac next to it.

en Ewoud …
Ge, Wheaten, Michel and I are all dutch and we already went true many rabbit holes in the past.

same in this post :

With 5v and 3.5A i should be safe.

I use the power supply of audiophonics in all my last built streamers, never had any problems with it, it must have sufficient cooling and at least 7 volts dc input but not higher than 9 volts dc. I’ll post something here tonight about how or what.

all i ment to say is that the pimoroni is not usefull with a max of 2.5 amp in your case
and you better go with the other one.

hey michel good morning :slight_smile:

am busy at the moment. will put here tonight how the best power on / off raspberry pi

it must use at least 3 amps otherwise you will get problems, especially with a large screen.

Since I already have a power supply my preference of course is to find a solution to use a power on/off button with that. I planned to use a remotPi board but that is discontinued.

This is not really an option because I will need another power supply

module wise there is not a lot at this moment only this one ( 5v / 7amp ) :

or in the netherlands here but is out of stock

btw the psu that you have is 5v but how many amps does it have?
maybe a link to it so we could see what you have.

Gekocht van een vriend die met een ander project bezig is maar een verkeerde had gekocht en mij leek deze prima.

okay, then I’m not going to explain how and what about this power supply if you’re going to use another one.

So, if I want to power the raspberry pi on and off with a switch there’s only this option?

Or use another power supply with this:

That are the two only options?

you mean the only one option the audiophonics is 7-12 volt and has a stepdown converter
you only have 5v if that goes true a step down converter you will have maybe 3volts left i hope.

The 5V power supply is enough theoretically. But this isn’t suitable for use with a stepdown converter, I understand that. But with the powerblock should work. PowerBlock - Raspberry Pi Power Switch | The Pi Hut
Or am i missing something? The input is 5v but the output is also 5v if the specsheet is correct.

I would first have a look at that forum for problems with that conscious power block you are talking about.
also you have to manually install a script.
