30Amp 7V-35V SmartDrive DC Motor Driver (2 Channels)


This is SmartDriveDuo-30, with the convenience of accepting the RC ( radiocontrol ) signal to drive two DC brushed motors in independent or mixed mode, it is perfect for combat robots. Not to mention it supports up to 80 Amps peak current (1 second) and 30 Amps continuous current on each channel, best for medium power motor. And with that, it is smart enough to accept the control signal from:

  • RC (Radio Control)
  • PWM from microcontroller
  • Analog voltage from potentiometer / variable resistor / joystick
  • UART data from microcontroller

The operating mode is determined by the configuration on the DIP switch, refer to the user manual for detailed settings. Not to forget, to make it RC receiver friendly, we added 2x3 header pin, with only 2 x RC extension cable (which is included), the wiring is done, it only takes 2 minutes! And by default, MDDS30 is configured in RC controller, mixed operation mode, even easier! With the MDDS30's wide operating voltage range, you can now connect two SLA batteries in series to power your motor, as it has an input of up to 35VDC supports. And you only need one power input to operate the motor and driver. Don't worry, the 3 cell and the 6 cell Li-po battery are within the operating voltage :) Hey! It also comes with low battery warning, what else do you need? What motor is good to be powered by MDDS30? As long as the engine:

  • Is DC brushed motor (two terminals)
  • Operating voltage from 7V to 35VDC
  • Rated current <= 30A
  • Peak current <= 80A


  • Bi-directional control for double brushed DC motor.
  • Support motor voltage of 7V to 35VDC .
  • Maximum current up to 80A peak (1 second), 30A continuous, each channel.
  • Onboard MOSFETs are switched on 18kHz for silent operation.
  • Regenerative braking.
  • Built-in error LEDs to indicate: (each channel)
    • Input error (blinks 2 times)
    • Undervoltage warning (blinks 3 times)
    • Surge protection (blinks 4 times)
    • Over temperature protection (flashes 5 times)
  • Thermal protection.
  • Current limit protection.
  • Multiple input modes:
    • RC (Radio Control)
    • Analog voltage from potentiometer / variable resistor / joystick
    • PWM and DIR (character size and locked anti-phase) of microcontroller
    • Serial simplified or serial packaged from microcontroller
  • Grove compatible connectors for control input.
  • RC (Radio Control) friendly connectors.
  • Built-in push buttons for quick test and manual operation.
  • Built-in LED indicators for error, RUN, overcurrent, motor output, for each channel.
  • Dimension: 81.28mm (W) x 101.60mm (L) x 42mm (H)

Customer questions

Q The Netherlands LucasI have 2 DC motors (11.5V, 120W, 2800 RPM). I don't know the peak current, will this 30A version suffice or should I get the 60A version? View 1 answer   |   Answer this question
