Yes, I did that before when using the normal receiverpi and worked perfectly.
It should be OK. But please just don't forget the GND.
Please find the attached StationPiPro schematic for more details. You can debug the issue by referencing to the schematic.
Good weekend.
Never forgetting the ground I know. 🙂 Already checked all several times.
I will try again. Don't know why it is not working...
Strange thing is that at pin 9 and 10 there should be 3v3 but there isn't...
Good weekend as well.
And I have it sorted out! I2s is working. Had a broken wire😮
Now to check why I don't see the settings of the fifo q7 on the monitorpi.
But that's for tomorrow.
Thanks for your replies, always fast and correct.

Hi Ian
I think I may have over ordered
Using the Station PiPro. FifoQ7,Dual Mono DAC
This is how I was going to power up for the first time
Station Pro:- 5V Dirty Side 5V Clean Side
Fifo Q7 3.3V
Daul Mono Dac - 3.3V
Have I doubled up?
If I have doubled up what is the best way to power the Fifo Q7 3.3v Direct or 5V from the clean side of the Station PiPro?
Thanks
Eddie

Station Pro: 5V Dirty Side and 5V Clean Side
OK, but if you want you can also share to save a 5V, but up to your decision.
Fifo Q7 3.3V
Yes
Daul Mono Dac: Three 3.3V
Three 3.3V, or share
Hello Ian,
I have tested a standard lineair +-5v on the IV stage and everything is working. Then I move back to the UcPure and changed the input supply to a new transformer with a dual 12V AC . First fully charged the UcPure and swithing on the UcPure. Everything is working again. But if the UcPure change from charging to conditioning mode the fuse of the -5v blows out when the IV stage is connected. If I change the -5 UcPure to +5V and vice versa, the other UcPure is blown out. (Still the -5v)
The fuse is also blown out of the -5v when I switch the whole system on at ones and the UcPure switch is also on and not fully charged. I will test what happens when there is no load on them of the IV stage but still connected to each other with the common GND.
2) When LifePO4 Mini's are fully charged the conditioners are working normal. In general it is working and I don't have problems with them, they only behave unexpected.
Please advice because the LittleFuses are not cheap ;-)
Greetings, Berry
Hello Ian,
Even without load the fuse of the powersupply which should deliver -5V is blown out if it is connected with the other UcPure for the common GND and switch to pure mode.

I think I have solved the problem. Because I received one the UcPures with a broken physical switch, I have used the cable to switch on the UcPure with broken switch with the first UcPure. But I have connected both outputs together. (see picture) I have changed it and now it seems to function normal!! At powering the whole system on and the UcPures are switching to pure mode, the fuse do not blow out. I am very happy for now, now it is time for some serious listening.
Hi Ian,
Today happy listening to the pro setup.
I also checked everything why i cannot change the Fifoq7 settings with the monitorpi. Checked S1 at the bottom of the Q7. It is still default off as it should be.
What else could it be? i ran out of options to check😊
Many regards,

Ho Ian,
Yes, both XO frequencies are shown and installed to the non-isolated GPIO.
Will attach picture when I get home.

Q Advr,
You can change the FifoPiQ7 settings as long as you can see the XO frequencies on the MonitorPi OLED screen.
Please see the p7 of Q7 users manual for details

Hi Ian,
I have a first generation TransportPi running on top of a FiFoPi Q3 module. Can you tell me if it makes sense to change it to a TransportPi mkII? I see that instead of the Asahi Kasei AK4104ET a Wolfson WM8805 chip is used now. What can you say about the differences in the sound of the new board?
