Next monday the 28th the most parts for the UI board and more will arrive from mouser, in week one and two of next year I reserved day's off and asked if I could use a workstation on my QRL to solder the parts with small pitch under the microscope. I still have to order the buttons and headers, so the pictures in Arturs post #539 will com handy.

Merry Christmas, a happy new year and best wishes to you all, your family and friends

Those 100uF tantalum capacitors make my head suffer...
According to photos of assembled board, looks like almost every (except UI board) 100uF capacitor is B3528 case
and 16V, is i'm right? And only one place where it can be purchased is Ali, mouser dose not have this capacitors in 3528 case.
Trying to find where is 10v or 16v is too tricky.

Thank you for link, Artur.
But i can't realize the count of 10v tantalum versus 16v tantalum and 6v of all range of tantalum capacitors.
It is would better to label voltage on the board, just my thought.

On schematics i found 16 of 100uF - 16v capacitors, but on board only 5 of tantalum D size(can be 100uF and 16v) and 3 of electrolytic, sum of 8.

Hello, Artur!


also, in your semiconductors BOM, for PCB1 described 2xLM1117 3V3, but on board is 5v, where is truth?

O kondensatorów, to znaczy wszystkie kondensatory typu B jest 10V i wszystkie typ D jest 16V w tym projekcie?

The 100uF tantalum on the UI board is part of the 12V rail an should be chosen 16v, I found some on the Mouser site. The 220uF and 470uF are part of the 5V rail and could be chosen 6V rating. But I chose 10V and also found them on Mouser.

Above is what I ordered for mainly UI board PCB3 from Mouser.

Hello, Remi.
It is not a problem to find D case capacitors of 100uF for UI board, but look at the TRX board. There is over 30 pcs of 100u capacitors on it and
all of them B type, but according to schematic, it must be 8 of them of 16v.

---

Clearly spoken, by schematics it must be 51 100u capacitors (15 of 16v, 36 of 10v and 6 is unknown voltage order), but on board i'm has find
only 44. This suggests that Arthur has made significant amendments to the schematics, which is reflected on the board, but not in the schemes.
Or i don't understand something. Those capacitors the only one thing that keeps me from make a last parts order.
Here i upload schemes with caps marked on it
Red circle - 100u 10v
Blue circle - 100u 16v
Yellow circle - all others

Artur, to byłoby bardzo pomocne, jeśli dokonać prostej listy BOM dla Kondensatory tantalowe, w tym typu przypadek, pojemności i napięcia.
To jest naprawdę zbyt trudne, aby dokonać właściwego wyboru, bez rzeczywistego schemacie. Dziękuję!!!
