1 :
i only use the Lis3dh ,and remove all other elements
2: i use the power 3.0V, i use multimeter test the current consume between VCC and GND
get the test result current is 16 μA,
(the spec says ,the device automatically enters power-down mode, and current is 0.5μA)
3, then i add the R1,it used for wake up the MCU,and connect to Lis3dh int 1 port ,
then a test the current like before ,but get the current is 56μA, it is beyond my imagination .
so i want to ask ,is there anything wrong ?why i cannot get the power down mode current consume like spec says ?

Bump.
Seriously this is a really major issue and till now I have been unable to find a proper solution to it......
One solution the guy claims is here but that has not worked for me.
