    I am also attaching the Xplained pro schematic for your reference.

    HI,

    I am having exactly same issue as yours. Did you got a solution? The current is exactly 188 uA.

    No.

    I am still waiting for a reply from the bosch sensortech team.

    Hi mmurty,

    You can refer to other threads where I performed design review, such as :
    https://community.bosch-sensortec.com/t5/MEMS-sensors-forum/BNO055-power-on-reset-issues/m-p/8644/hi...

    I had a look at your schematic and indeed I see that BL_IND is tied to GND. This is a digital output that indicates when the bootloader is running, the I/O pin may have been damaged by the 0 ohm to GND. Can you rework your board to remove R18 ?

    The recommendation to increase the capacitance to 1uF on Pin 9 is also valid for you.

    HI,

    I exactly did the same thing. Please find the attached schematics. Even the current consumption is 180 uA. Also is performance affected if I supply 2.5volt instead of 3.3v rail? Circuit.JPG
