There is plenty of room, the recom is smaller than the TI part in my picture..

The MB-6582 needs 2 or 3 power rails. 5V and 9 or 12V for the SIDs (or both in a mixed environment). You always use the 5V recom since it is much more efficient than the 7805 and generates no heat. You could use a 9V one in a mixed SID environment where you have a linear Vreg for the 12V rail (meaning a supply volage of ~ 15VDC), 6V is a lot to burn off as heat..

They are installed. Gray tint, it hides everything but the illuminated stuff

And Done!

There are plenty of efficient switching 5V regulators out there.

Ok, this is officially closed for lack of interest. I'll get the files and BOM up on the Wiki.
I do have some extra boards from my runs:
2 x Jack/Dout PCBs with one SRIO connector (for anyone not interested in the TPD addon)
1 Stuffed Jack DOUT PCB, tested as working (from my prototype)
1 AOUT euro PCB
1 Jack/Dout PCB with the extra SRIO (for TPD euro)
I'll let these go at cost (10$ each for the PCBS, $35 for the stuffed one), first come first served
-
adafruit stocks a bunch of different ones in square
-
So this is the result: The way this is hooked up is My SEQV4 hooked up to the Aout Euro module via D-Sub, the euro module is powered by the eurorack power and has a SRIO out connection to the TPD. 5V is generated by the Aout Euro

Testing successful! All good. I'll post some pics and video shortly. Ilmenator brought up the point that the 4 buttons and LEDs dont have an official function yet so this might be a good time to discuss that..
-
I suspect the PS and SHL may be relevant here as well but I am far from a display expert to have any input on those

something is different from the Winstar parts, I have those in mine and changing to 0x02 did the trick. Had the same issues with one not working.
-
I used a 3904 for my design, maybe that's the difference. The circuit works fine in the module..
-
it doesnt really matter what you use, this is how I did it:
-
I've got a PCB with the chip soldered. PM me if you want it
-
I havent used a core32 in a long time so I cant comment on that but yes, the midijunction drivers. The current STM core works fine
-
I havent had issues on 10 or 10AU but I am using the ploytec driver (1.3.3 IIRC), I DID have issues with the "Midibox GM5" one which is 2 version older than the current one. That being said, I still have the GM5 disappearing issue with multiple interfaces (I have 3 5x5s), I had some correspondence with ploytec about this and he said it was a USB hub issue with my motherboard but I dont buy that, it's a bug with the chip for sure. I've had these interfaces across 4 motherboards, various add-in USB cards, different hubs, 4 operating systems and the issue persists without fail. It's a nuisance more than anything but it would be nice if they acknowledged and fixed it.

not even a dozen ppl. We will see what happens when with the TPM but this may just end up as files on the wiki for people to use.
-
nice. well done
-
No, its about half that size with finer pitch
-
the DACs are MSSOP which is fine pitch SMD. You dont need anything high powered but a fine tip is recommended. If you have not done anything like this previously, I recommend a practice board off ebay. The DACs are $22 each so you dont want to screw those up.
-
Just a quick follow up, I simply snipped the +5V pin on the Dsub connector and powered it from the euro module, works fine..

yep. Switching is fine, linear ones tend to get really big
