The SmartDriveDuo Smart Dual Channel 30A Motor Driver is one of the latest smart series motor drivers designed to drive medium power brushed DC motor with current capacity up to 80A peak (few seconds) and 30A continuously, each channel. This driver is designed especially for controlling differential drive mobile robot using RC controller. Nevertheless, MDDS30 also can be controlled using analog joystick or microcontroller (PWM, Serial).

A good controller that can be used with rc or a processor.

A good controller that can be used with rc or a processor.


Used on my robot. Really good, no any problems. Easy to install and set.

Better than I expected.

This being my first board I have nothing else to compare it to. That said I was impressed with the versatility of it. I could upgrade my motors and batteries and use the same board. I'm very happy with it.

Very robust driver

It is a very robust large motor driver with a lot of oomph. One minor drawback is that it will keep spinning the motors slowly when the analog signal is lost. We fixed it with some pull down resistors on the signals.

This controller is overkill

I bought this controller for my {40lb } Robot Tank project and its is work better then i expect! Highly recommend! Quality of this part is unbelievable! You know what you pay for!
