Mode 2: R/C Input
R/C input mode takes two standard R/C channels and uses those to set the speed and direction of
the motor. There is an optional timeout setting. When timeout is enabled, the motor driver will
shut down on loss of signal. This is for safety and to prevent the robot from running away should
it encounter interference and should be used if a radio is being used to control the driver. If
timeout is disabled, the motor driver will continue to drive at the commanded speed until another
command is given. This makes the Sabertooth easy to interface to a Basic Stamp or other lowspeed
microcontrollers.
