This is SmartDriveDuo-30, with ease of accepting RC (Radio Control) signal to drive two DC brushed motors in independent or mix mode, it is perfect for combat robot.  It supports up to 80Amps of peak current (1 second) and 30Amps continuous current at each channel, best for medium power motor.


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)

    Cytron stuff is highly recommended

    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.

    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.
