    Hey Shu-Cheng,

    Everything on our device looks good. The device address is correct at 0x70h.

    1) Just to be sure you have pull up resistors tied to SDA/SCL_BL(1,2,3,4).

    2) INT0,1,2,3 are okay to have one pull up resistor.

    3) The 10uF caps are a bit of an overkill. You don't need that much. It should still work though.

    Thanks,

    -Bobby
