EVAL-M355-ARDZ-INT headers installed incorrectly

Hello Michal,

Today I tried to assemble the second unit of our gas analyzer prototype. I used exactly the same hardware and to my surprise it didn't work, I couldn't even turn it on. After a review and finding nothing missing, disconnect the sensors with the CN0429 boards, connect the power and the system start normally. If I reconnected the sensors, the system would shut down as if I suffered some kind of electrical problem (short circuit).

Looking carefully at the EVAL-M355-ARDZ-INT board in prototype 1 and prototype 2, I realize that in the second all the connectors were welded upside down (see photo). The board that works correctly says to be assembled in the USA while the other does not indicate where it was assembled. The lousy production quality control system that Analog Device is having is inconceivable.

I urgently need a way to return the defective boards EVAL-M355-ARDZ-INT and EVAL-CN0429. I really feel disappointed by the situation

Alain

    Hi Alain,

    Sorry for this trouble, but can you provide me some information please.

    Which board in the image you sent has the connectors populated in the correct orientation?  Can you also please tell me where you purchased your EVAL-M355-ARDZ-INT?  I'm going to try and help you get another board as fast as possible but I need some information first.

    Cheers,

    Brandon
