Power terminals
0V and 5V
The 0V and 5V connections are
used to power and interface to
low-power control circuits.
The 5V connection is a 5v
power output. This is useful
for supplying power to low-
current devices, such as a
potentiometer or a radio
receiver. The 5v terminal is
capable of supplying 100
milliamps if the source battery is 12.6v or less. If the source battery is greater than 12.6 volts, the
5v terminal is capable of supplying 10 milliamps. If more power is needed, we recommend using
a ParkBEC or DESW050 to supply the needed 5V power to the rest of the robot.
The 0V connection is the signal ground for the Sabertooth. In order to receive input signals
correctly, it must be connected to the ground of the device sending the signals.
Using the 0V and 5v connections to power a radio receiver in R/C mode and potentiometer in
analog mode is shown in Figures 2.1 and 2.2. If you are using multiple Sabertooth 2x5s running
from the same radio receiver, only one should have the 5v line connected.

The 5V terminal can be used to power small loads, like a
potentiometer or a radio receiver. The 0V signal must be
connected to the ground of the device generating the input
signal.
