Sabertooth  Dual 12A Motor Driver for R/C is a dual motor driver specifically optimized for use in radio controlled vehicles. It is suitable for medium powered robots, cars, and boats.

Out of the box, it can supply two DC brushed motors with up to 12A each. Peak currents of 25A are achievable for a few seconds. Overcurrent and thermal protection mean you’ll never have to worry about killing the driver with accidental stalls or by hooking up too big a motor.

This special R/C edition of our motor driver comes with options for exponential control, autocalibration, and built-in mixing. The operating mode is set with the onboard DIP switches so there are no jumpers to lose. 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 vehicle a quick and nimble edge.

Sabertooth has a built-in 5V Switching BEC that can provide power to a microcontroller or R/C receiver and a servo or two. 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 transistor is the switch at ultrasonic speeds (32kHz) for silent operation.

If you need more advanced control features, check out Sabertooth 2X12. For something smaller, check out Sabertooth 2X5 R/C.

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.
