It turns out that the 5v signal on the PWM connectors is V_MOTOR,
which by default is connected through to V_ROBOBATT. So as long as you
leave the jumper wire in place, then you can power your robostix
through that connector.

I'm not exactly how the connectors go on the Sabertooth, but you can
also connect up to either the V_MOTOR or V_ROBOBATT connectors as well
(if that makes things any easier for you).
