Hello,
I am mounting the computer (ALESTE PCB 2018) and I do not have the reference of U5.
Would it be possible to have the reference of the U5 component?

Thanks a lot.
Best regard
Irios
Can you point out where in the board is the ic ?, a picture if possible ?.I don't have any Ux components on the BOM.

  • It's not broken, it just hasn't been fixed yet.

U5 means IC5, but check anyway in case the chips are numbered differently on different versions.

Hello,
Thank you for your answers.
Below are the photos of the board and the U5 component.

I looked at all the diagrams on the net but there is no mention of this U5 component.
Is it an interface that has been added? Is it maybe an LF amplifier?

Thank you for your help

Hi sorry but you are building the other version of the aleste board that is for replacement of the UKNC one.
I can't help you on this chip.
You can ask on https://zx-pk.com/forum/ theres a thread in there about assembly this particular board.
