WARNING: The Cytron engineering team has discovered that some BECs sold online, claiming to be 5V supplies, are actually 6V. Please do not use supplies of 6V or higher in conjunction with the controller's 5V pin, as doing so will damage the MCU of the controller.

SmartDriveDuo-30 is a versatile and powerful motor driver for combat robots, capable of driving two DC brushed motors in independent or mixed mode with ease via RC signals. With a peak current support of 80Amps per channel (1 second) and a continuous current of 30Amps per channel, this motor driver is ideal for medium power motors.

SmartDriveDuo-30 is perfect for a wide range of applications, including:

  1. Combat robots, for driving multiple motors with precision and ease.
  2. Robotics and automation systems that require a mix of independent and combined motor control.
  3. RC vehicles, such as remote-controlled cars, boats, and aircraft.
  4. Industrial control and automation processes, for precise and responsive control of multiple motors.
  5. Agricultural and mining equipment, for smooth and efficient operation of multiple motors.
  6. Remote control lawn mowers, for easy and efficient control of cutting and moving.

This motor driver is smart enough to accept a control signal from:

  • RC (Radio Control)
  • PWM of microcontroller
  • Analog voltage of Potentiometer/Variable Resistor/Joystick
  • UART data of microcontroller

This motor driver is suited for a brushed dc motor with the following specifications:

  • Operating voltage from 7V to 35VDC
  • Rated Current <= 30A
  • Peak Current <= 80A


  • Bi-directional control for dual brushed DC motor
  • Support motor voltage from 7V to 35VDC
  • Maximum current up to 80A peak (1 second), 30A continuous, each channel
  • On board MOSFETs are switched at 18 KHz for quiet operation
  • Regenerative Braking
  • On board Error LEDs to indicate: (each channel)
    • Input Error (Blinks 2 times)
    • Under Voltage Warning (Blinks 3 times)
    • Over Voltage Protection (Blinks 4 times)
    • Over Temperature Protection (Blinks 5 times)
  • Thermal protection.
  • Current limit protection
  • Multiple input modes:
    • RC (Radio Control)
    • Analog voltage from potentiometer/variable resistor/joystick
    • PWM and DIR (sign-magnitude and locked-antiphase) from microcontroller
    • Serial Simplified or Serial Packetized from microcontroller
  • GROVE compatible connectors for control input
  • RC (Radio Control) friendly connectors
  • On board push buttons for fast test and manual operation
  • On board LED indicators for Error, RUN, Over current, motor output, for each channel
  • Dimension: 81.28mm(W) x 101.60mm (L) x 42mm (H)

    Smart drive Lower wheels

    Posted by Ricardo Duran on Jul 15th 2022

    I installed this in a Wild thing power wheels that was practically given to me but it had a blown circuit board. Installed this motor driver and it’s so much fun, it can actually carry me, I can remote control the power wheels with an RC controller and I also added a joy stick. To switch nether en them I do have to plug two wires and flip a dip switch. But mainly use. Lots of fun, now I’m wondering where else can I use it.

    Cytron stuff is highly recommended

    Posted by Dan Benson on Jun 7th 2020

    I use this dual channel contrioller for my autonomous lawnmower build. The motors are from a motorized wheelchair. I'm extremely impressed with Cytron products. This unit is very high quality. The price is really great. And their tech support is the best! Highly recommended. You can't go wrong.

    Cytron smartdrive duo 30 amp

    Posted by Dan Benson on May 23rd 2020

    I'm using this on my autonomous lawnmower. The motors are from an electric wheel chair. The controller is a Pixhawk running ardurover. This controller is about the best price and capability you will find. It is extremely well made, and does everything I want it to and more. If you're building any type of robot you should definitely consider this driver. And makermotor was great. Very fast shipping.
