Hello,
I started my journey when I bought a new DAC with digital input only. So, I wanted to have some portable device with digital out but, with an acceptable price.
After looking for this during hours, I realized the less expensive way to do that is with RPI plus your DIGI.
Now, I'm waiting for the part to come and I was thinking if, by the way, I could assemble the RPI with both DIGI and your DAC at the same time (eventually, with an expansion board).
Could you please, instruct me how to do that and what parts do I need besides the two I've mentioned before?
I was thinking in a DIY PSU linked directly on digital out card with 5V. But, with this plus, how/where should I connect the PSU and under which power (voltage and max current) this should be done?
In advance, I'm sorry for some "English language error", but I'm Portuguese.
Thank you

HiFiBerry team Dear Paolo,
with the old DAC and the old Digi (not the +) version, this works. You need to stack them on top of each other and only configure the Digi driver. However you need to replace the header with a stacking header. We recommend this only for people with very good soldering skills. Otherwise there is a good chance, that you will damage the board.
You can connect an external PSU to the board. However it will power the card AND the Raspberry Pi. It should be able to provide at least 1A current.
Best regards

Paulo Relíquias Hi Daniel,
Thanks for the reply. The question refers to DIGI+ and DAC+ (my fault didn't mentionate it). Is that possible?
If so, could I connect it with a IDE strip, avoiding soldering needs?
The PSU should connect to DAC+ or to DIGI+?
Thanks again
PS:My name is Paulo, not Paolo (italian name) ;) -
HiFiBerry team Dear Paulo,
sorry, but with the DAC+ and Digi+ there is no possibility to use both boards in parallel.
Best regards

Paulo Relíquias Hello again,
I received my RPI yesterday and tried to make it work. I installed picoreplayer (downloaded from hifiberry), and after instalation, the message is: waiting form html requests (something like that).
I can acces via web browser (got IP from advancedIP scanner), i see every options.
Since I tried to connect with RPI using Orange Squeeze and Logitech Squeeze with no success, I'm asking for help in these two questions (could not see the answer in this (or other foruns):
1-Should I do some customizations or the default options should be working (even without optimization, using 3,5 mm jeck analogue output for example). Putting in another way, after instalation it's not supose to connect RPI with my android smartphone with this app (Orange squeeze)?
2-Witch app should work better (or work at all) with RPI.
Thank you, and I'm sorry to bother you with newbie questions. -
HiFiBerry team Hi Paulo,
we don't provide a picoreplayer image. Did you download it from the PiCorePlayer page? The newest release should work with both DAC+ and Digi+. What the problem of the non-responsive web server is - I have no idea. You should ask the piCorePlayer developer about this. Maybe he can give you a tip.
I can't tell which app works better, but I know that many people are happy with piCorePlayer.
Best regards

tobimess2000 Hello,
I'm definitively new with HifiBerry and Rasperry too.
I want to buy a Raspberry Pi B+ and also want to use both - the Digi and the DAC output - for my project.
I understand to use the old versions of both.
My question:
is the
HiFiBerry Digi – transformer output
the right choice for the Digi output?
Another question:
I want a small LCD showing the mp3 tags of the tracks.
Is that possible e.g. with the
Adafruit Blue&White 16x2 LCD+Keypad Kit for Raspberry Pi ?
Thanks a lot. -
tobimess2000 ... sorry I forgot:
I want to use Volumio.
Does the
pre-packaged Volumio Version
support the old versions of the DAC and Digi boards?
Thanks a lot. -
HiFiBerry team Dear Tobi,
Volumio supports the older Raspberry Pi B boards.
About your display: you need a software that supports this or you have to write your own. This is nothing that will work out-of-the-box. A user did something like this before: http://i2.wp.com/www.hifiberry.com/wp-content/uploads/2014/03/RPi-HiFiBerry-2014.jpg
Do do this, you should have electronics and programming skills, otherwise I would not recommend this.
Note that you have to solder the cables to the DAC or Digi board as you can't simply connect a board on top of it.
Best regards
Daniel -
tobimess2000 Thank very much you for your answer.
OK - I will not continue the thing with the display ;)
I think the older Raspberry B will do it.
I just want to have an audio media center an nothing else. I have different amplifiers in use,
so I do need the two boards for the output.
But:
With other software like Raspbmc I can use the Raspberry B+ with the older DAC and Digi (without +)?
You wrote above (7th October):
You need to stack them (the DAC and the DIGI) on top of each other and only configure the Digi driver. However you need to replace the header with a stacking header
Is this the right way to build in the two boards an can I use the stacking headers offered in the shop?
Is a differenz in quality between the old DAC/DIGI an the versions with + ?
Thanks in advance. -
HiFiBerry team Hi Tobi,
the old boards for the Raspberry Pi A/B will not work on the B+.
To stack a DAC and a Digi you can use the stacking header from the shop. Note that you have to unsolder the original connector first. However there is a risk that you damage the board while unsoldering the old connectors. This is only for people who are very good in soldering. Also you do it on your own risk. There is no warranty for boards that have ben soldered onto.
Another option is just using 2 Raspberry Pi's.
If you want to output the same stream onto 2 amplifiers, an Y cable will also work (except if the input resistance of the amplifiers are extremely low which is usually not the case). This is much easier to do and I would strongly recommend this instead of stacking 2 boards.
Best regards
Daniel -
tobimess2000 Thanks for the time you spent for your advices.
I will follow your idea and will first build a RaspberryPI with a single DAC.
Seems to be the best way as you recommended.
And maybe later another one with the DIGI board.
Thank you again and best regards. -
Marco Buslacchi Hello Daniel,
For connect both cards (DAC + DIGI) on raspberry B, I must replace only the header (26pin) with a stacking header or also the P5 header (8pin)?
Thanks for the moment -
HiFiBerry team Yes, especially the P5 header. Note that there is a risk that you damage the board when replacing the header. We do not recommend this! It will also void the warranty!
Best regards
Daniel -
tobimess2000 @ Marco
Please note here, when you've done it.
@Daniel
It's really necessary to desolder the 26pin stack?
The video on your page: my impression, that the 26pins do not have
any function for the Dac only to fasten it. The 26Pin don't have to be soldered on the Dac (Video).
Well, may be it's working too if you solder the 5Pin via cable only
and build in the Dac separately e.g besides the RasPi mainboard... in
another bigger case...
Thank you. -
tobimess2000 Sorry, I meant, soldering only the 8Pin (EIGHT) via cbale to the DAC... and build in the Dac separately... -
HiFiBerry team For the old DAC, only the 8-pin header connection is needed. However all other board also use signals from the 26pin connector.
Best regards
Daniel -
tobimess2000 Daniel, thank you very much.
Have a nice weekend. -
Marco Buslacchi Hello Daniel and tobimess2000,
thanks for your replies.
I have a raspberry b and a DAC and a DIGI boars.
So in conclusion if I put digi board on raspberry fixing it by normal header (26pin GPIO + P5) and from the digi board I solder 8 wire to dac board. Can does it work?
Have a nice evening
Marco -
HiFiBerry team This can work.
Best regards
Daniel -
Marco Buslacchi Hello Daniel,
Thank you very mutch.
As soon I will create my system I will write here my result.
For the moment I tried only the DAC and the sound is great...
Thanks
Marco -
tobimess2000 Marco,
thank you for your pioneer work!
I think you will have an interesting and very good result. -
Scottblackman Resurfacing this thread to see if anything has changed regarding the use of a Digi+ and a DAC+ Pro on Raspberry Pi 3 GPIO pins at the same time? Can this be done? Don’t each of these boards have a unique address enabling them to both be addressed by the GPIO board?
I building an audio player based on RuneAudio and would love to be able to use both cards in my project.
-
HiFiBerry team The GPIO does not have any "adressing" scheme. Everything that is connected to a GPIO is connected to it. This isn't a bus system designed to support multiple boards like a bus in a PC.
We might come up with a combination board sometimes in the future, but it will never be possible to combine a DAC+ Pro and a Digi+. This is simply impossible from an electrical point of view.Best regards,
Daniel -
Scottblackman Good to know. Thanks for your insight Daniel.
