Dear, On the KIT MAX R 10 10M08 Eval Kit Board is it possible change the voltage of the regulator EP5388QI from 3.3V to 2.5V? The VCC_CORE can be 2.5V for the proper operation? I not using the Arduino or Opamps circuits from this board.

Dear, Just to check , the idea is remove the R4 and connect an external board regulator on the J2.

Its possible? The FPGA partnumber used on this board said that this is a Single Supply and can work with 3.3V on core and 2.5V on VCCIOs.

Best regards,

Daniel.

    ​Hi Daniel,

    Yes, We can remove the R4 and use J2.2 for external supply.

    VCCIO is not monitored by POR so we can supply it any time we required. example : We can also power up VCCIO for IO banks individually after configuration based on our design requirements.

    So, I am not seeing any problem, But however Intel will not be liable for any damage that you may occur as a result of modification, either with or without your knowledge.

    Regards
