Can you ask Andymark to stock USB to Stranded cables so that we can wire it to the 5v 500 mA port of the VRM?

The VRM is supposed to be able to supply stable power with battery voltage down to 5V. Is the navX board protected from reverse voltage on the USB Port? If not, it would be nice if you could do that in a future release.

Thanks.
Actually, this seems like a simple, inexpensive option that also alleviates the reverse polarity concern. Here's one w/a built-in Mini-B USB connector.

We'll go ahead and test the Duracell charger (or one like it) to make sure it does the trick, and post the results on this thread.
