1. INTRODUCTION
SmartDriveDuo-10 is one of the latest smart series motor drivers designed to drive medium
power brushed DC motor with current capacity up to 30A peak (few seconds) and 10A
continuously. This driver is designed specially for controlling differential drive mobile robot
using RC controller. Nevertheless, MDDS10 also can be controlled using analog joystick or
microcontroller (PWM, Serial). MOSFETs are switched at 16 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-10’s feature makes driving a robot with differential drive a truly plug and
play experience.
Some of the features for SmartDriveDuo-10 are summarized as below:
●Bi-directional control for dual brushed DC motor.
●Support motor voltage from 7V to 35V.
●Maximum current up to 30A peak (few seconds), 10A continuously.
●16 KHz switching frequency for quiet operation.
●Battery low voltage indicator.
●Battery over voltage indicator.
●Thermal protection.
●Multiple input modes: RC, Analog, PWM, Simplified Serial and Packetized Serial.
●On board push buttons for fast test and manual operation.
●No polarity protection for V motor.

FUNCTION Description:
Motor RIGHT LED Indicator
Indication for current flow and direction for motor RIGHT. If LED MRA turns on, means
current flows from output MRA to MRB. Vice versa.
Motor RIGHT Terminal Block
Connect to motor RIGHT at your mobile robot. User can tie the wire to the terminal block or
solder the wire directly to the pad at bottom layer.
Power Supply Terminal Block
Connect to power source. User can tie the wire to the terminal block or solder the wire
directly to the pad at bottom layer. No polarity protection, please double check before
power up.
Motor LEFT Terminal Block
Connect to motor LEFT at your mobile robot. User can tie the wire to the terminal block or
solder the wire directly to the pad at bottom layer.
Motor LEFT LED Indicator
Indication for current flow and direction for motor LEFT. If LED MLA turns on, means
current flows from output MLA to MLB. Vice versa.
Mode Selection DIP Switch
User can select different input mode by setting the DIP switch.
Motor LEFT Test Button
Fast test to check driver functionality for motor LEFT. If MLA is pressed, current flows from
output MLA to MLB. Vice Versa.

5. POWER SUPPLY
SmartDriveDuo-10 supports input voltage ranges from 7V to 35V. The recommended power
sources are:
●6 – 18 cells NiMH or NiCd battery.
●2 – 6 cells LiPo or Li-Ion battery.
●7V – 35V sealed lead acid battery.
●7V – 35V power supply (Must be in parallel with a battery with same voltage).
The power source can be connected to SmartDriveDuo-10 either via the terminal block, or
soldered directly to the pad at the bottom layer. There is no polarity protection on
MDDS10, please double check the connection before connecting to power source.
NOTE:
1. If a power supply that cannot sink current is being used (example: bench top and AC to
DC switching power supply), the input voltage will rise when the driver is regenerating
(motor is slowing down). Thus, it is important to connect a battery with same voltage in
parallel with the power supply to absorb the current generated by the motor. Else, the
input voltage might rise to a level where SmartDriveDuo-10 will be destroyed
permanently or the power supply trigger protection mode.

6. MOTOR CONNECTION
Similar to the power supply, connection to the motor can be made either via the terminal
block, or it can be soldered directly to the bottom layer pad.
For Mixed mode, especially for RC input mode (or Breakout board with Joystick soldered),
each terminal block must be connected to the same side of the motor. For example, left
terminal block connected to motor LEFT and right terminal block connected to motor
RIGHT. Then, user can test it by controlling the motor by using RC controller. If the motor
give wrong direction, reverse the polarity of the motor connection at the terminal block.
