The Sabertooth 2X25 is a versatile dual DC motor driver capable of supplying up to 25A continuous (50A peak) per channel. Suitable for high-powered robots up to 100lbs in combat or 300lbs for general-purpose robotics, it features synchronous regenerative drive that recharges batteries during braking and reversing.
Controllable via analogue voltage, R/C, simplified serial, or packetised serial, with independent and speed+direction operating modes set via on-board DIP switches. Screw terminal connectors mean no soldering is required. A built-in 5V BEC powers your microcontroller or R/C receiver, and lithium cutoff mode enables safe use with Li-ion and LiPo batteries.
Key Features
- Dual 25A Channels – 25A continuous, 50A peak per channel

Jargon buster
Plain-language definitions for the technical terms used above.
- DIP switch
- A DIP switch is a small set of physical on/off switches used to configure hardware settings without software. It matters because changing features such as auto power-on or charging limits may require moving these tiny switches correctly.
- LiPo
- A lithium polymer rechargeable battery commonly used in portable electronics projects. It matters because LiPo batteries need correct charging circuitry and care, and this board includes hardware intended for that battery type.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- motor driver
- An electronic circuit that lets a low-power controller switch and control a motor that needs more current than the controller pins can safely provide. Checking motor driver support matters because pumps and motors usually cannot be connected directly to a microcontroller output.
