Board design deference between Rev C3 and Rev C4 for MIMXRT1170-EVK (i.MXRT1170 EVK)

ksugai — Thu, 09 Jun 2022 05:49:41 GMT

There is a label which is described "SCH-32171 REV C4" on the top side of MIMXRT1170-EVK I have. "REV C4" seems revision code for the board design files.

When I download the MIMXRT1170-EVK-DESIGNFILES from NXP official website, it contains a file of schematic which name is "SPF-32171_C3.pdf".

I think "SPF-32171_C3.pdf" is the schematic for REV C3. So I'd like to confirm the schematic for REV C4. Or I'd like to know what is the difference between REV C3 and REV C4.

Hi @ksugai

Could you please share one photo about your Rev C4 MIMXRT1170-EVK board?

Then I will help you to check it internally, and find the related schematic, as we also using the Rev C3 board now. How do you get the Rev C4, buy it directly from the NXP and distributor?

Best Regards,

Kerry

Hi @ksugai ,

Thanks so much for your cooperation.

I already help you to check with our internal expert.

You totally can refer to the Rev C3, as the schematic and the PCB is totally the same, just one point to the C4:

FXOS87OO is EOL, so rev C4 take is as DNP, others are totally the same.

Schematic just use C3.

Wish it helps you!

Best Regards,

Kerry
