Hi all,

   Now i am working with lsm9ds1, i2c communication is used for data read/write, and my application code worked with lsm9ds1 breakout board or evaluation board.

But when i try the same code in my circuit(see image), no acknowledge received from sensor.

found some difference between my circuit and breakout board circuit

   1.10uF capacitor(c2) in breakout board circuit, is it necessary?.

   2. batch code are different

            breakout board,

               2730

               9S1

               LSQBG

            In my circuit,

               2713

               9S1

            MNPEO

Is both are same?

vdd and vddio are shorted in both circuit.
