Features
Dual motor driver with mixed and independent options
Sabertooth 2x32 will drive two motors at up to 32A continuous and 64A peak each. These can be mixed
together for a tank drive type vehicle, or run independently. It can be controlled by analog voltages, R/C
transmitters, TTL serial commands, USB, or a combination of these signals.
USB input
Every third generation Sabertooth motor driver comes with USB standard. This makes operating from a
PC or advanced microcontroller as easy as plugging in the cable. Windows drivers are included with the
DEScribe PC software, and no driver is required for Linux. USB is also used with to set options, create
custom operating modes, monitor the system, and update the firmware with new features.
Auxiliary inputs and outputs
Sabertooth 2x32 has two additional 8A power outputs, which can be set up to operate electromagnetic
brakes on motors, act as a voltage clamp to protect power supplies, or power other medium duty loads.
Sabertooth 2x32 also has extra signal inputs and extra serial ports which enable better control options.
User-created operating modes for custom applications
We often hear that a motor driver would be perfect if it only had one more input or a minor operating
change. Third generation Sabertooth motor drivers like 2x32 have user-scriptable operating modes,
which allow you to mix and match analog, R/C, serial and USB inputs, create custom output functions
and handle tasks automatically. You can even switch control from one input type to another. Many jobs
that would have taken an additional microcontroller can now be handed with just the Sabertooth 2x32.
Self-tuning PID control using the optional Kangaroo x2 expansion board
When used with the optional Kangaroo x2 expansion board, Sabertooth 2x32 works with quadrature
encoder or potentiometer feedback for speed or position control. Because it is self-tuning, you can skip
the hours or days of work getting your PID coefficients dialed in.
High resolution Synchronous regenerative drive with ultrasonic switching frequency
Sabertooth 2x32 features high resolution inputs and over 4000 output speeds for the smoothest control
on the market. The switching frequency is over 29 kHz, so there’s no annoying motor whine. The
outputs use synchronous rectification for high efficiency and low heat generation, as well as
regenerative drive to save energy and extend battery life.
Adjustable current limit, ramp rates and thermal protection
The current and temperature limit of the Sabertooth 2x32 can be set for each motor channel. This can
be used to protect the mechanism of your device, as well as protect itself.
Easy mounting and setup
Sabertooth 2x32 features a new heat sink CNC machined from a single block of aluminum. Mounting is
accomplished with included 4-40 hardware. All connections are by screw terminals, so no soldering or
special cables are required, other than the included micro USB cable.
