I am working on Overo Fire with Palo35 expansion board.
I got a problem when I tried to measure the power consumption of the whole board.
I connected my ammeter serially in the power cord, but the machine could not boot. I guess reason was that the impedance of the ammeter itself is non-ignorable compared to the impedance of the board. It draws the input ampere. So my question is what should I do if i want to measure the ampere and voltage?
BTW, there is a video online called "disabling the Wifi on the Gumstix Overo Fire" where they measured the ampere and voltage. Is there anyone who can tell me how they did that?
I would be very appreciated if anyone can help me or give me any suggestions. Thank you.
