    Modifying the CY8CKIT-049-42XX prototype board for 3.3V operation

    arun.john

       Hi,

         

      I have the CY8CKIT-049-42XX prototype board, this board (with the USB-serial bridge) derives its power from the USB port (+5V DC). 

         

      I would like to change the operating voltage to 3.3V, as this makes it easier for me to connect to 3.3 VDC based modules without connecting any level shifting hardware.

         

      Is the block scheme shown shown in the image workable ??

         

      thanks
