Zedboard Power with Current Sense

eactor
eactor over 12 years ago

Hello,
did anybody try to estimate the power consumption of the Zedboard using the onboad current sense J21?
If I but my Osciloscope on the those pins I'm measuring 3.2mV?
But how does that relate to the power drawn?
P=U^2/R  -> With the resitance beeing 10mOhm?
Using this would result in a power consumption below mW which seems unrealistic.
Cheers

I also checkt if the board is sneaking power elsewhere USB, PowerOverEthernet ... but without luck

    Thanks for clarification!
    Lol I was calculating the power consumption of the Resistor thatu2019s great :-D
    Actually I'm not running the default setup, but on that matter I inserted the original SD card and also measured 3.2 mV. So my design doesn't differ a lot considering the power consumption. But it runs a Linaro Ubuntu with some PS peripherals routed to EMIO and not a lot within the FPGA otherwise.
    Cheers
