kw41z power consumption

Use SDK example "power manager(A)" and "smac low power node(B)" to test power consumption
Use Hardware FRDM-KW41Z- ver A3  
Measurement point is SH504

Question:
1. Why is there such a big difference in power consumption between the two(A.B)? What are the main reasons?
2. Both(A,B) are below VLPS, why can't the power consumption drop anymore?

Hi Daniel,

Be sure that you are disabling the Pins that you are not using. The SMAC exampe is calling the buttons,led, SPI and I2C init pins.

Please look at the pin_mux.c file.

Regards,

Mario
