• Dual motor controller - 25A 6V-24V 
• Analog, R/C, simplified serial and packetized serial interfaces (TTL)
• Synchronous regenerative drive
• Ultra-sonic switching frequency (32kHz)
• Thermal and overcurrent protection
• Lithium protection mode

The Dimension Engineering Sabertooth Dual 25A Regenerative Motor Driver is one of the most versatile, efficient and easy to use 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 brushed DC motors with up to 25A continuously. 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 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 speed + direction operating modes, making it the ideal driver for differential drive (tank style) robots and more.
