Re: [Gumstix-users] What's soldered to FB2 on my Breakout-GS?

The FB is supposed to be a ferrite bead. If it's present, then you can
power the breakout-GS from USB. You can tell the difference by the
following:

1 - The ferrite beads tend to be square in cross section. The
resistors tend to fairly flat in comparison.

2 - The resistors have their resistor code written on them as a 3
digit number. You'll see a couple with 103 (10K) and 203 (20K). The
ferrite beads have no writing on them.

As to whether they're shipped with them by default or not, somebody
from gumstix would need to comment.
