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 more.
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 BEC that can provide power to a microcontroller or
R/C receiver. The lithium cutoff mode allows Sabertooth to operate safely with
lithium ion and lithium polymer battery packs - the highest energy density
Sabertooth's transistors are switched at ultrasonic speeds (32kHz) for silent
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 motor
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.
