In you case do you need another MCK from fifo to DAC board? In addition to trasportpiAES? See two manual screenshots

OK,
you have a real mess here.
You don't need SHIELDPI PRO II here, you do not need the ESS Controller Extension Kit but Ian's GPIO extension kit if you have MONITORPI PRO II, UCCONDITIONER MKII Ultra Capacitor Conditioner Board 5V and MAXWELL Supercapacitor 2.7V 325F and are not needed here because you have PUREPI II.
First assemble the STATIONPI PRO according to the instructions, look for How to share one 5V power supply with J3 and J5 in the manual on page 9 and do it according to the instructions.
RECEIVERPI PRO II goes directly Under the RPI, on the clean side go Q7, on Q7 go TRANSPORTPI AES Ultra, then DUAL MONO PLUS DAC ES9038Q2M HAT Raspberry Pi / I2S, then OPA861.
With PUREPI II 3.3V on FIFOPI and DAC, then PUREPI 5V on STATIONPI PRO II J5 or J3 but only on one, never on both.
"The MCLK clock cable from ES9038Q2M should go to FiFo Q7, but I use this connector already for my Transport PI AES" >> FIPOPI q7 has two master connectors, one is above, the other is below on the other side of fifopi and you can also use it for DAC and for Transportpi.
You still lack +/-5V for OPA861, there you should have taken 2x LinearPI + 2x 5V UCCONDITIONER and 4 Maxwell capacitors, I would also add one 3.3V UCCONDITIONER + 2 Maxwells for DAC and FIFOPI Q7 3.3V
PM me directly, and I can explain everything.

Hi,
which XO do you have exactly, do you have a specification, manual, pictures?
I am a newbie too.
I was able to solder ultra capacitors (UC) on UcConditionner board with a 75W iron at 425C.
Gabster has a YouTube video showing what to do:
You have to heat the pin first and then heat the board at the last minute before putting the solder.
You have to take care to prevent burning the board.
I did 1 pin on one UC then one pin on the other UC to make sure I don’t overheat anything.
Patience is the key here.

Thank you for raising the issue with ShieldPi, I was not sure it was supposed to be there.
I have a similar setup except for the DAC part.
I have a UcPure (3.3v) to feed clean FifoPiQ7 and the UcConditionner+ LinearPS (5V) to feed StationPi. This is my understanding.
Two UcPurePi also works thou.
i can assure you that it was not a user error. because i showed him the whole schematic too...and i built x players with the parts from ian
Short protection sounds like it detected a short.
I find there is a lot of caution required to put all of this gear together. Ian is a circuit and board designer. “We” are the DAC designers trying to figure out how to assemble his gear into a working solution.
There are a lot of options in his gear. There are a lot of small things to properly do - like snipping long solder legs so they don’t touch a board below and short out or use proper spacers and standoffs the right length - which he does mention in the manuals if you read them 10 times. It’s very easy to mistakenly short things out is what I have found if you aren’t careful. Also there isn’t built in protection for dumb things like inverting polarity and protecting dumb moves that as “DAC designers” we maybe should know. Like putting clocks in backwards.
Most problems I make are due to assumptions of thinking I know how something goes together when that isn’t true. Or from not reading the manual. Or just from doing something stupid late at night.
I find when Ian ignores things , it’s because he knows I messed up or knows I didn’t read something properly and that if I am really stuck and ask nicely he generally helps out.
Many thanks again. I lost track of time, it's already October. Just seems like yesterday, I was finishing up my Ian Summer Project. Once October ends, there will be no more Raspberry Pi 5s available for consumers until 2025-2026. Maybe never. The Commerical entities will snatch them all up with their unlimited budgets. Fortunately, Eben (RPi Owner) is looking out for consumers with the pre-orders. So I got lucky reading your timely post, I could easily of missed knowing there is a Raspberry Pi 5 out in the wild since I'm in brainless mode, "Production Mode". I don't like to think about my gear and just listen after I finish a Project.
2024 would of been miserable without my RPi 5s. I wouldn't know what to do.
What I love is the improved Memory Latency:
I run everything in RAM. My whole OS loads in RAM, so you can pull out the USB stick after loading and it still runs normally. All my well-mastered tracks run exclusively in RAM, so this improved latency is definately something I look forward as I'm all about low latency at the UcPure level, kernel level, output level and I guess now RAM level. I have zero leaks in my chain for an Authentic to the Master Source Tapes experience. With the added CPU PWR and lower Memory Latency, it's just going to make that experience that much better. My head is spinning now knowing how easily I could of missed grabbing an RPi 5. It would of taken an RPi 6 in 2027 to recover.
My physical media will always be more valuable to me than the hardware. But the hardware is at the forefront of technology so all good.
Too many have holes in their chains or flaws to incorporate a RPi 5 so they are best to stick with RPi 3 or RPi Zero. Their gear is pretty, but not robust or CPU PWR enough. It's all about being off Mains. It's 2023, who is still on Mains? That's Mickey Mouse. No wonder they have to stay on RPi 3.
Good luck with Foxconn moving into town. Maybe more future tech leaks upcoming. Back to collecting well-mastered stuff (more important) instead of thinking about gear....

Ah, well, like 99.999% of most people.
Even audio enthusiasts!
Why, if I turn my UCPure off or unplug the charging power, doesn’t the blue light stay on and deliver power until the super caps run out of stored energy? It seems to just kill the power and the blue light goes off.
I thought they could play music for some time to use up the stored energy but I can’t seem to disconnect it from the power brick while it does this.
When hooked up to power brick and playing music continuously, Every couple hours the blue light goes off for five minutes and back on. Assume super caps ran out and are recharging while brick is sustaining the music.
Also what does sync mode do? I don’t have it set up but it seems to keep recharging automatically without hooking up sync cables.
Power newbie. Amazing stuff but I still don’t understand how it works.
Main reason to know is safely transporting the UCPure. How do I run the caps down by just playing music till they’re dead.

I am trying to answer my own question here ….
Is it because the UCPure board has a relay to isolate the caps from any active circuit and that relay needs power to operate to either isolate and provide power via caps or charge caps and provide power via the board - thus requiring power to do anything? No power to board no music regardless of the cap charge???

please stop telling me that i have connected it wrong...i am not a dac designer either...i have built many machines...i have completely rebuilt ian's parts in 3d, i know the boards inside outI get the error when the board is not connected, and also when I connect something and have load on the output...the short protection always comes up...and the board has burnt

Hello,
I had the short circuit warning with the big lifepo4 board after being switched of for two months because of holiday.
Maybe because the system got kind of depleted. After a few days just trying to switch it on suddenly it worked again.
But i already made the decision to trash the board. It seems there are more people having issues.
So i ordered some new boards like ucpure, purepi, Q7 hope this time there wont be any issues. Don't want them to end up in the bin aa well
Greetings Eduard
