i'm not sure. But I do know that other designs that were based off the TelosB state that it is a bad idea to power from the USB with batteries installed. Other designs provide a jumper that switches between usb power and bat power.
The safe thing to do is remove the batteries. Or pull the TelosB schematics, I don't remember where they are, and study the problem. If you try to find the schematics and fail, let me know, I have them somewhere. But please do try to find them yourself first. eric On Thu, Mar 24, 2011 at 1:11 PM, Joey Wilson <[email protected]> wrote: > All, > > I have a question about the TelosB battery power.
