1. INTRODUCTION AND OVERVIEW
MD10B is an enhanced version of MD10A. It is designed to drive high current brush
motor or application. It is designed for wide range of robotics and automotive applications.
The board incorporates most of the components of the typical applications. With minimum
interface, the board is ready for plug and play. Simply add in power, this driver is ready to
drive high current motor.
It has been designed with capabilities and features of:
•Industrial grade PCB with heavy copper material for high current applications
•Each component is soldered properly and tested
•Support up to 10A maximum
•5V logic level compatible inputs
•12V as Vcc
•PWM speed control up to 10KHz
•Bi-directional control for 1 motor
•Very low standby power consumption
•System ground is isolated from motor’s power source using opto-isolator
•4 Schottky diode as clamping diode

Power Battery Input
Power source for motor. It can be as low as 5V and as high
as 19V. The driver does not have protection against wrong
polarity on power input, thus user must be careful during
providing power source to this driver. Please follow (+)
and (-) marker on the PCB for the correct polarity.
Motor Motor Terminal Terminal for motor connection.
12V Operating supply Input for driver logic operation. User should provide 12V

Voltage controller input pin. These two pins control the
state of the relay in normal operation according to the truth
table 4.1 (brake, clockwise and counterclockwise).
PWM Pulse Width

Voltage controlled input pin. This pin is isolated using
opto-isolator. It will control the onboard MOSFET to ON
and OFF further control the speed the motor.

A – Connecter for motor.
B – Connector for power supply.
C – Power supply indicator LED. It is green in color. Once power is inserted to the board,
this LED will turn ON.
D – 5 ways header pin for external connections. If this kit is connected to microcontroller
board, it should be powered with 12V. Please refer to hardware installation for detail
connection.
E – Relays are used as switch to change the direction of motor (clockwise or anticlockwise).

5. INSTALLATION (HARDWARE)
5.1 Connecting Battery and Motor
In a typical application, the motor power supply (battery) should be soldered to
connector provided. The control pin come with connector and is ready for user to interface
with wire.
12V should be supplied (to12V pin) for this driver for logic operation. CW and CCW
control the activation and direction of the motor, while the PWM pin turns the motor on or
off for speed control. CW and CCW will activate the on board relay. Thus providing 5V
using a switch or relay to these 2 pin can turn on the relays further drive the motor. As for
PWM pin, user may provide a constant 5V to it if no speed control is required.
5.2 Connecting to Microcontroller
Typical Application Circuit for DC to 10KHz PWM Operation

5.3 Connecting to switches (without microcontroller)
Typical Application Circuit using switches (no speed control)
5.4 Reverse-battery
The motor driver boards do not have any protection against reverse-battery. If user
connects the battery or power source wrongly it will damage the on board clamping diode
and further burn the driver. Thus please be careful during making connection.

6. GETTING STARTED
For this section, MD10B will be interface with PR10. Please refer PR10, DIY project from
Cytron website for details example using MD30B. PR10 shows the method using MD10A;
however MD10B have been designed to be compatible to MD10A, user may refer to this
project. This DIY project also shows the method to writing program to use MD10B. Link to
PR10 is http://www.cytron.com.my/PR10.asp
