Hi,<br><br>alix boards don't have such a current meter on-board.<br>About your goal, I'd rather take a scope and view the 5V supply of the USB at different input voltages, starting at 5.0V going up to 20V. Also you should compare with different power supplies. <br>
You shouldn't limit your power supply to what it just needs.<br>Please let us know your findings.<br><br>Best regards,<br>Michael Steinmann<br><br><br><br><div class="gmail_quote">2012/1/22 linux123 <span dir="ltr"><<a href="mailto:24bits@comcast.net">24bits@comcast.net</a>></span><br>

<br>
I am using Voyage Linux MPD Version: 0.8 (Build Date 20111030) with an Alix<br>
2D2 board for my music server which connects to an Ayre QB9 external USB<br>
DAC. I was wondering if there are any ways to view/ monitor actual power<br>
usage of the ALIX board via software based sensors included with this Linux<br>
distribution or thru add ons? I saw that there were some basic Temp sensors<br>
available but nothing about power usage..etc<br>
<br>
My primary reason for seeking this information is that I am powering my Alix<br>
board with a laboratory grade benchtop linear power supply that is variable<br>
from 0-30v. At the moment I am feeding it a little over 15.5v & .33mA but<br>
can't tell how much of that power it is actually using without breaking out<br>
a volt meter/clamp. Its not the end of the world if I have to do it this way<br>
but thought it would be much easier if it could be done via software<br>
instead. My goal is to feed the board exactly what it needs to run and<br>
supply power for the USB port and not a spark more as to keep electrical<br>
noise/interference to a minimum.<br>
<br>
Thanks for your time and any info you can provide.<br>
