    Re: BNO055 power on reset issues

    HI,

    I exactly did the same thing. Please find the attached schematics. Even the current consumption in suspend mode is 180 uA. The Bosch flyer board gives 3.3uA with same code. In low power mode, my board gives 500uA and flyer board gives 145uA. Also is performance affected if I supply 2.5volt instead of 3.v volt rail?

     

    Regards,

    Performance is not affected by voltage. At 2.5 volts, the sensor would operate at maximum performance.

    The current consumption does not include the crystal, i2c communication, or the current flowing through R39 due to internal pull-up on COM3 pin. (see Table 4-6)

    Can you confirm current measurement and config ?
