Outputs
Sabertooth 2x32 is a dual motor driver, and can drive two motors at up to 32 amps continuous and 64
amps peak current per channel. In addition, there are two 8 amp auxiliary outputs and two 20 milliamp
indicator outputs.
Motor Outputs
Sabertooth 2x32’s M1 and M2 motor outputs are 12 bit, synchronous regenerative motor drives. They
have a switching frequency of 30 kHz for silent operation. Each channel has a programmable current
limit. It is also possible to disable regeneration to drive loads like lamps or anodizing tanks, or
completely disable the outputs and braking to allow motors to freewheel.
Typical motors used with a Sabertooth 2x32 include fractional horsepower permanent magnet motors,
wheelchair type motors, scooter type motors and brush type cordless tool motors. Most two wire,
permanent magnet motors can be made to work. Sabertooth motor drives have also been used to drive
large solenoids, lamps, heaters, coolers, electromagnets, shakers and transducers. To minimize heating
and losses, use as large a wire to your motors as is practical. 12 gauge is typical for short wiring runs.

Indicator Outputs
Two of the signal inputs, S2 and A2, can be used as 20 milliamp, 3.3 volt outputs. This is typically used to
drive LEDs for remote control panels or signal back to microcontrollers. The indicator outputs are
