Cytron SmartDrive MDDS30A 30A Dual 7V-35V DC Motor Driver (Peak 80Amp)

Cytron SmartDrive MDDS30A 30A Dual 7V-35V DC Motor Driver (Peak 80Amp) is SmartDriveDuo-30, with the ease of accepting the RC (Radio Control) signal to drive two DC brushed motors in independent or mix mode, it is perfect for combat robots. Not to forget it supports up to 80Amps of peak current (1 second) and 30Amps continuous current at each channel, best for medium power motor.

And with that, it is smart enough to accept the control signal from:

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

We know DC brushed motor is widely used for many different applications; from conveyor, AGV (Automated Guide Vehicle), mobile robot and combat robot. One of the reasons is the ease to use it, just connect the two terminals of motor to power respectively, it will start rotating, so simple. Yet, to control the speed and direction from a controller, a motor driver is needed.

The operation mode is determined by the configuration on DIP switch, please do refer the User’s Manual for detailed settings. Not to forget, to make it RC receiver friendly, we have added 2x3header pin, with just 2 x RC extension cable(which is included), the wiring is done, it takes only 2 minutes! And by default, MDDS30 is configured in RC controller, Mixed control mode, even easier!

With MDDS30’s wide operating voltage range, you can now series up two SLA battery to power your motor as it supports up to 35VDC input. And you only require one power input to operate the motor and driver. Don’t worry, 3-cell and 6-cell Li-po battery are within the operating voltage 🙂 Hey! It also comes with battery low voltage warning, what else do you need?

Suitable motor that is good to be driven by MDDS30:

• Is DC Brush motor (Two Terminals)
• Operating voltage from 7V to 35VDC
• Rated Current <= 30A
• Peak Current <= 80A

Note: The new revision of MDDS30 (Rev 1.2) changes the 2×3 header pins from right-angle to straight-angle. It is an effort to strengthen the header pins from drop off.
