K70 System-On-Module (SOM) Power Consumption

Here is some information regarding power consumption of the K70 System-On-Module (SOM). All numbers listed in this note are mA @ 3.3V.

Here are some measurements from various practical Linux configurations running on the K70 SOM:

SOM Configuration	Test	Power Consumption
SOM-K70	Linux running shell on serial console Ethernet unplugged Linux idle at serial console	133
SOM-K70	Linux running shell on serial console Ethernet enabled Linux idle at serial console	151
SOM-K70	Linux running shell on serial console Ethernet enabled Linux copying a file from a development host over NFS	196

Also, please refer to Linux Low-Power Mode on Kinetis for detailed information on power consumption of the K70 SOM in low power mode.

To provide an upper limit on possible power consumption of the module, here is the Theoretically Calculated Max Power Consumption of the K70 System-On-Module (SOM-K70 variant).
