Sabertooth dual 25A motor driver
The Sabertooth 2X25 is one of the most versatile, efficient and
easy to use dual motor drivers on the market. It is suitable for
high powered robots - up to 100lbs in combat or 300lbs for
general purpose robotics.
Out of the box, the Sabertooth can
supply two DC brushed motors with up to 25A each. Peak
currents of 50A per channel are achievable for a few seconds.
Overcurrent and thermal protection
means you'll never have to worry about killing the driver with
accidental stalls or by hooking up too big a motor.
Sabertooth allows you to control two motors with:
analog voltage, radio control, serial and packetized serial. You can build many different robots
of increasing complexity for years to come with a Sabertooth.
Sabertooth has independent and speed+direction operating modes, making
it the ideal driver for differential drive (tank style) robots and
The operating mode is set with the onboard DIP switches so there are no
jumpers to lose. Sabertooth features screw terminal connectors - making
it possible for you to build a robot without even soldering.
Sabertooth is the first synchronous regenerative motor driver in its class.
The regenerative topology means that your batteries get recharged
whenever you command your robot to slow down or reverse. Sabertooth
also allows you to make very fast stops and reverses - giving your robot a
quick and nimble edge.
Sabertooth has a built in 5V 1A Switch-mode BEC that can provide power to a microcontroller
or R/C receiver, as well as 3-4 standard analog servos. The lithium cutoff mode allows
Sabertooth to operate safely with lithium ion and lithium polymer battery packs - the highest energy
density batteries available.
Sabertooth's transistors are switched at ultrasonic speeds (32kHz) for
Sabertooth 2X25 uses 1.3 milliohm MOSFETs in its bridge. Going by our
competitor's ridiculous rating schemes this would make it a dual 190A
Use of our motor drivers with cheap AC adapters is not recommended.
Use a battery or at least put a battery in parallel with a DC supply.
