1.0 INTRODUCTION

SHIELD-MD10 is an Arduino shield for controlling high current brushed DC motor up to

10A continuously. It is compatible with Arduino UNO, Arduino Duemilanove, Arduino

Mega , Arduino Leonardo and possibly other pin compatible main boards. SHIELD-MD10 uses full solid state components which results in faster response time and eliminates the wear and tear of the mechanical relay. SHIELD-MD10 shield has stackable side headers which allows for more Arduino shields to be stacked on top of it.

SHIELD-MD10 Shield come with these features:

●

●

●

Bi-directional control for 1 brushed DC motor.

Support motor voltage ranges from 7V to 25V.

Maximum current up to 10A continuous and 15A peak (10 seconds).

●

●

●

●

●

●

3.3V and 5V logic level input.

Solid state components provide faster response time and eliminate the wear and tear of mechanical relay.

Fully NMOS H-Bridge for better efficiency and no heat sink is required.

Speed control PWM frequency up to 10KHz.

Stackable I/O header pin.

Selectable digital pins for PWM and DIR.

Product User’s Manual – SHIELD-MD10

1. Stackable Digital I/O Headers

JP4 and JP6 are Digital I/O pins stacked to the Arduino main board.

2. Optional External Control

External control is for the use of other types of microcontroller besides Arduino.

3. Test Button B

When this button is pressed, current flows from output B to A and motor will turn CCW

(or CW depending on the connection).

4. Test Button A

When this button is pressed, current flows from output A to B and motor will turn CW (or

CCW depending on the connection).

5. Stackable Analog Input Header

This is the analog port of the Arduino and is not used by SHIELD-MD10. The stackable header allows other stacked shield to utilize these pins.

6. Stackable Power Pins Header

This is the power port of the Arduino. Only RST and GND pins are connected to the

SHIELD-MD10. The stackable header allows other stacked shield to utilize these pins.

7. Reset Button

Product User’s Manual – SHIELD-MD10

Reset button is for the convenience of user to reset the Arduino main board.

8. Red LED B

Turns ON when the output A is low and output B is high. Indicates the current flows from output B to A.

9. Red LED A.

Turns ON when the output B is low and output A is high. Indicates the current flows from output A to B.

10. Green Power LED

Turn on when the SHIELD-MD10 is powered up.

6.0 HARDWARE INSTALLATION

This section shows the example of using SHIELD-MD10 with Arduino UNO as the main controller to control a brush motor. However, other Arduino main board such as Arduino

Duemilanove and Arduino Mega can also be used.

Figure below shows that the SHIELD-MD10 is stacked on the Arduino UNO. Please ensure that the pins alignment is correct.

Select the pins for PWM and DIR. The default PWM pin is set to D3 while the DIR pin is set to D2. However, other pins may be selected if these pins are already used by other application. Remember to initialize the correct Arduino’s digital pin accordingly in the user firmware.

Product User’s Manual – SHIELD-MD10

Connect the brush motor and motor power to the terminal block on SHIELD-MD10 as shown. Don’t forget about the power source for the Arduino main board too.

Power up the Arduino main board and load the firmware first before powering up the

SHIELD-MD10 motor driver shield.

Example source code can be downloaded from the SHIELD-MD10 product page at Cytron’s website.
