Thank You for the Reply. I just need to power my sabertooth with an additional +5v, I think.

If you put a 5v regulator from either your ez-b or your battery it could work.

Why do you need to power your sabertooth with 5V? It's input voltage is whatever your motor needs are .... from about 6 - 24 volts.... It gets it's power from the battery you plug into it... The sabertooth can't run anything off of 5V...You only need 2 wires from the ezb.... Signal wire to S1 of the sabertooth and the ground wire... It does however, have a 5V bec to power other devices like a radio receiver.... You really should download the manual and have a read.... before possibly wiring it wrong and ruining it....

Richard, now that you point that out...

MOVIE MAKER! Don't wire the 5 volts from the sabertooth to your ez-b port!

Like Richard said, all you need the the signal cable to s1 on the saber and the ground.

Nice catch Richard.
