Quickstart board Vin current rating

Tried to look up the specs myself but downloads are in a strange .odt format which I can't open?
I'm trying to find out the maximum current draw that the tracks on the quickstart can cope with when drawing current from the Vin pin.

    It's Open Office format. Free download:

    There should be a PDF copy on the product page, but it is missing. I checked our internal network, and we have the file, so I'll let our web department know it is missing, and they'll get it up soon. Until then, I've attached a copy.

    Thank you kindly David
    Thanks Publison I wasn't aware it was an open office format, unfortunately I have installed it before but had a lot of trouble on my XP machine so uninstalled it but thanks anyway.

    Just read the pdf file but it doesn't state how much current, looking at the tracks I don't think it would be much but are we talking at least an amp?

    Skylight, what are you trying to do exactly? Are you talking about the Vin pin on the 40 way header, or somewhere else?

    I've been driving these led strips using a 10A PSU using a quickstart protoboard, which feeds power down to the quickstart main board (via the Vin pin on the header), but only at a few hundred mA or whatever the Prop itself needs. Are you trying to run something hefty via the USB lead as a power supply?

    I've got the same question, if anybody has any ideas. I thought it would be really nice to be able to power some small 5V things with the Vin pin on the header when powering the board with USB. I was thinking up to a few hundred mA shouldn't hurt anything, but would like to hear to from someone with more QuickStart experience before I try it.

    refer to the last page of the Quickstart pdf...

    Iin rev a - 80 Mhz all cogs running = 11 ma
    Iin rev b - 80 Mhz all cogs running = 9.8 ma
