Sabertooth 2x32 V1.1 Dual 32A Regenerative Motor Driver with Overheat and Overcurrent Protection
VAT inclusive; Computed calculations added locally.
Overview
The Sabertooth 2x32 V1.1 from Dimension Engineering provides a flexible solution for controlling two high-current brushed DC motors in robotics, mobility platforms, automation equipment, and other demanding applications. Its synchronous regenerative drive system supports both efficient motor operation and regenerative braking.
The V1.1 version increases the continuous current capability to 32A per channel and expands the nominal operating voltage range to 6–30V compared with the previous version. The controller can accept several control interfaces, including analog signals, radio-control inputs, plain-text or packetized serial commands, and USB.
For more advanced systems, the Sabertooth 2x32 provides configurable user operating modes, current limiting, auxiliary power outputs, and real-time USB monitoring. It can also be paired with a Kangaroo x2 motion-control module for closed-loop speed or position control using suitable encoder or analog feedback.
With thermal and overcurrent protection, battery protection features, and multiple configuration options, the Sabertooth 2x32 V1.1 is suitable for projects where flexible dual-motor control and higher current capacity are required.

Important Notes
- The stated 32A continuous and 64A peak ratings are per channel.
- Do not exceed the specified 33.6V absolute maximum supply voltage.
- Actual motor current capability depends on motor characteristics, wiring, cooling, duty cycle, and operating conditions.
- Regenerative braking can return energy to the power source, so the battery or power system must be suitable for regenerative operation.
- Select the appropriate control mode and configure the controller before operating the motors.
- For closed-loop position or speed control, an additional Kangaroo x2 module and suitable feedback device may be required.
- Product dimensions and specifications should be verified against the applicable manufacturer documentation before integration into a safety-critical system.
