1. INTRODUCTION 
SmartDriveDuo-30 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 specially 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 mode and thermal protection. 
“SmartDriveDuo-30’s feature makes driving a robot with 
differential drive a truly plug and play experience” 
Some of the features for SmartDriveDuo-30 are summarized as below: 
●  Bi-directional control for dual brushed DC motor. 
●  Support motor voltage from 7V to 35V. 
●  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. 
●  Battery over voltage indicator. 
●  Thermal protection. 
●  Current limit protection. 
●  Multiple input modes: RC, Analog/PWM, Serial Simplified and Serial Packetized.
