[[AxelEVB-Lite|AxelEVB]] integrates a chip (Texas Instruments INA226) that allows to measure the power consumption of the Axel SOM. This component - referenced as U25 - is very flexible. Following are the instructions to perform basic measurements. For more details please refer to its data sheet (http://www.ti.com/product/INA226).
TBDSOM power consumption measurements are available to be read from userspace. Following are the ''sysfs'' entries for:* Voltage (mV):<pre>root@axel-lite:~# cat /sys/class/hwmon/hwmon0/device/in0_input5root@axel-lite:~# cat /sys/class/hwmon/hwmon0/device/in1_input3286</pre>* Current (mA):<pre>root@axel-lite:~# cat /sys/class/hwmon/hwmon0/device/curr1_input425</pre>* Power (uW):<pre>root@axel-lite:~# cat /sys/class/hwmon/hwmon0/device/power1_input1500000</pre>
