Description
- Regenerative dual channel motor driver
- Current: 32A (continuous), 64A (peak per channel)
- Ultrasonic 30 kHz switching frequency
- Analog, R/C, serial, USB input modes
Sabertooth Dual 2x32A 6V-24V Regenerative Motor Driver is a dual channel motor driver capable of supplying 32 amps to two motors, with peak currents up to 64 amps per motor. It can be operated from radio control, analog, TTL serial or USB inputs. It uses regenerative drive and braking for efficient operation. A variety of operating modes including tank style mixing and automatic calibration allow most projects to work immediately out of the box.
In addition to the standard operating modes, Sabertooth 2x32 features additional signal inputs and power outputs, as well as enhanced configuration options. User-defined operating modes allow for custom operation, such as switching between radio control and computer-driven inputs on the fly, emergency stops or front panel control overrides. The auxiliary power outputs can be configured to allow the Sabertooth 2x32 to operate from a power supply without a parallel battery, or automatic control of electromagnetic brakes. When combined with Dimension Engineering’s Kangaroo x2 motion control module, the Sabertooth 2x32 can be used for closed-loop position or speed control with encoder or analog feedback. The state of the driver can be monitored in real time using the USB port in any operating mode, making debugging your project faster and easier. Sabertooth 2x32 is more flexible, robust and powerful than previous motor drivers, while also being easier to use.

Customer Reviews
This item works great in my R2D2.
and item arrived in a reasonable time.
Easy setup and operation, works perfectly.
When connected to Linux via USB, appears as a serial device. You can control motors, query battery, temperature, and various other features. It's a little difficult to use several in the same system at the same time because the order of the device allocation in Linux is not guaranteed, but you can set different addresses on each controller, up to 8 controllers, for a workable workaround.
I bought this hoping for an easy solution to building a differential drive robot. It did not disappoint. Works as intended right out of the box, just needs connections to battery, motors and joystick. And after switching the power on the robot is ready to move practically immediately - no waiting for the driver to boot up or anything. It is also very powerfull for its size, driving two 500W motors easily. The option to limit (scale down) speed by auxiliary signal is very usefull. I can control the robot slowly with milimeter precision in tight spaces and then move up to fast walking speed when in open spaces. The only downside i found was when I forgot to connect one axis of the joystick and the driver was in bi-directional mode. The internal pull-down to 0V means the missing output will be interpreted as 100% one direction. Having an 85kg robot start spinning madly in place just after power up is a bit scary. Make sure you power your robot up the first time with its wheels not touching ground :-).
Very strong for its size. The usb allows you to adjust settings on the laptop
