How do I jumper breakout-gs for USB powered operation? TIA, Doug |

You'll see an unpopulated pair of pads on the board labelled if memory serves "FB2" on the hirose side, near the large(r) IC -- if you solder a ferrite bead there, you'll have a usb-powered board.

Is it safe to jumper across those holes without a ferrite? I didn't get a wall adapter because I thought I had the right size power jack, but didn't, and I don't have a ferrite bead. Will the power source be too noisy without the ferrite? Just want to try booting while I wait for the proper power jack. -- Doug |

It'll probably work, and you're unlikely to fry anything in any case with the noise. It might cause some radio-frequency emissions from the board though, if that's a problem. Try it, and if it's not working, you'll be no worse off than you are now :) C On Jul 14, 2005, at 11:38 AM, Doug Sutherland wrote: > Craig Hughes wrote: > > > You'll see an unpopulated pair of pads on the board labelled if > memory serves "FB2" > > on the hirose side, near the large(r) IC -- if you solder a > ferrite bead there, > > you'll have a usb-powered board. > > Is it safe to jumper across those holes without a ferrite?
