  • Read datasheet again. ;)
    Vdd: 2.5V .. 3.3V
    Vdd IO A: 1.71V .. Vdd+0.1V
    Vdd dig M: 1.71V .. 2.0V
    Vdd I2C Bus: 1.71V .. Vdd+0.1V
    I use it with a 3.3V I2C bus without problem (and without level converter).
    Yes, the above schematic (and PCB too) is wrong.
    The good connection: the VDD dig M=1.8V and the others are 3.3V :)
    (Fig. 4.: LSM303DLH electrical connection 1 - recommended for I2C fast mode)

No public wish lists :(
