SmartDriveDuo Smart Dual Channel 30A Motor Driver
Description
- Bi-directional control for dual brushed DC motor
- Support motor voltage from 7V to 35VDC
- Maximum current up to 80A peak (1 second), 30A continuously, each channel
- On board MOSFETs are switched at 18 KHz for quiet operation
- Battery low voltage indicator
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).
MOSFETs are switched at 18 KHz to ensure quiet operation and no annoying whining sound. Besides, it also equipped with a microcontroller unit to provide smart features such as multiple input modes and current limit and thermal protection.
Features:
- Battery over voltage indicator
- Thermal protection
- Current limit protection
- Multiple input modes: RC, Analog/PWM, Serial Simplified and Serial Packetized
- 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
- 81.28 x 101.60mm x 42 mm (W x L x H)

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.
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.
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.
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!

To qualify for a refund under the 30-day return policy, all of the following conditions must be met:
- A valid Return Authorisation (RA) number must be obtained prior to returning the product. Returns without an RA number will be refused.
- The RA number is valid for 30 days. The returned item must be received within that period.
- The RA number must be included with the return.
- Products must be returned in unused, unmodified condition (e.g., no scratches, alterations, missing parts, or signs of installation/use) and in their original packaging, suitable for resale.
- Shipping fees are non-refundable. Return shipping costs are the responsibility of the customer, except in cases of a product confirmed defective through RobotShop's troubleshooting process or of a verified shipping error by RobotShop.
- Refunds are processed within 7 days after receipt and inspection of the returned item.
- A £100 cleaning fee may apply to domestic robots returned in used or unclean condition.
- A 20% restocking fee may apply to large-quantity returns of items ordered specifically for the customer from the manufacturer or not part of RobotShop's standard inventory.
Return Exceptions
The following products are not eligible for return or refund under this policy:
- Used, damaged, or modified products — Items that show signs of use, wear, or alteration, making them unsuitable for resale.
- Consumables * — Use and wear-and-tear components, altered or depleted through use (e.g., batteries, belts, brushes, gears, filament, tyres, disposable bags, lubricants, greases, waxes, etc.). Not eligible for return once opened or used.
- Perishables — Goods liable to deteriorate or expire rapidly. Not eligible for return.
- Sealed goods (health or hygiene) — Items sealed for health-protection or hygiene reasons (e.g., masks, gloves, odour-absorbing products). Not eligible for return once unsealed.
- Build-it-yourself products and items requiring customer assembly * — Including robots & kits, robot parts, and other products requiring assembly or soldering. Not eligible for return once assembled, soldered, or installed.
- Digital Goods, Software, and Apps * — Final sale only, due to licensing restrictions.
- Clearance Items * — Products identified as clearance or final sale, including end-of-life or discontinued items.
