[Lab] arduino mini pro queschin

[Darcy Whyte]

I really love these tiny arduinos but one thing is puzzling me.

If I plug it to USB, I can run servos off of Vcc.

So I can program it and test it while it's connected to USB.

But when I take the USB away and run it from battery it seems to brown out
with the servos running off VCC.

I had to wire the servos directly to the battery.

It's rather inconvenient to switch back and forth between USB and battery
configuration. Any tips for that?

Both ground pins are equivalent right?
