Hi everyone,

I'm using a LIS3D in my schematic. Everything works fine. I can read the register "WHO_I_AM" without any problem.

BUT : I have a current consumption of 1.2 mA. Can you help me ? I don't understand how is it possible.

Here is my schematic :

I'm working with an I2C interface.

Thanks for your help.

Best regards

    CS pin cannot be floating, if you use I2C connect the CS pin to VCC.

    R67 on SDO pin creates voltage divider with internal pull-up and the level won't be well defined.
