Power comsumption on Zedboard.
Posted: Wed Jul 15, 2015 8:18 am
Hi everybody,
I'm trying to measure power consumptin of a zed board thanks the 10m-ohm resitor on the main power line (connector J21).
Since I expect a consumption arround 6 W, I should have 500mA passing throug this resistor and I should measure a tension around 5mV.
However I measure 200mVwith the redpitaya? Does I have miss some calibration procedure or am I doing the measure wrongly?
My backgrounds in electronics and mesurements are very light and I'm sorry if my question is too naive!
Have good day.
