    The SyRen motor driver is one of the most versatile, efficient and easy to use motor drivers on the market. It is suitable for medium powered robots - up to 50lbs in combat or 180lbs for general purpose robotics.

    Out of the box, the SyRen 25 can supply a single DC brushed motor with up to 25A continuously. Peak currents of 45A 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.

    With just one SyRen driver you can control a motor with: analog voltage, radio control, serial and packetized serial. You can build many different robots of increasing complexity for years to come with a SyRen. Owning two SyRens allows you to build differential drive (tank style) robots because they can work in tandem with built in mixing.

    The operating mode is set with the onboard DIP switches so there are no jumpers to lose. The SyRen features screw terminal connectors - making it possible for you to build a robot without even soldering.

    SyRen 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. SyRen also allows you to make very fast stops and reverses - giving your robot a quick and nimble edge.

    SyRen has a built in 5V BEC that can provide power to a microcontroller or R/C receiver. The lithium cutoff mode allows SyRen to operate safely with lithium ion and lithium polymer battery packs - the highest energy density batteries available.

    SyRen's transistors are switched at ultrasonic speeds (32kHz), meaning no one will be able to hear your robot ninja army approaching.
