  Product Description
  
    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 20 can supply a single DC brushed motor
    with up to 20A continuously. Peak currents of 30A 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.
  
  
    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.
  
  
    Servo pigtails are available here.
