This ensures motors on the same side receive the same signal ("skid steering"). The Sabertooth's BEC can be used to power a microcontroller up to ~~1A. If additional current is needed, consider using a spare XT30 split off from the main battery to power the microcontroller and disconnect the 5V (red) cable from the BEC. |

| 27 | {{warningBox warningText="CAUTION: Before powering the motors, ensure they rotate in the same direction on each side. If the wiring between the motors and the Sabertooth was done correctly, the motors on each side of the robot should rotate in the same direction.<br><br>If the front and rear motors rotate in opposite directions however, the track which connects them will cause them to stall and burn very quickly! If you are at all uncertain, it is safest to remove the sprockets and test the motors. If they rotate in opposite directions, the wiring to the Sabertooth needs to be corrected. |
