DS160PR412-421EVM: After the 3rd use, board DS160PR412-421EVM no longer worked and the LED (D1) no longer lit up------ # 199417

Part Number: DS160PR412-421EVM

Hello Team,

One of our (Mouser Electronics) customers bought part DS160PR412-421EVM. After the third time usage, the board no longer worked and the LED (D1) no longer lit up.

Can you please advise on troubleshooting method?

Please see the picture of the board and kindly advise.

Best Regards,

  • Hi Usman,

    I don't see an obvious problem with the board from the picture provided. Do you know under what conditions the customer used the board?

    • What was the general background of the tests? What was different in the working case vs the non-working case?
    • How was the EVM powered? From an external power supply or from a system CEM slot?
    • Were any shunt settings changed from the default?
