Monster Motor Shield Driver 30A
Monster Motor Shield Driver 30A – This is essentially a ramped up version of our Ardumoto motor driver shield.
The monster motor shield comes with a pair of VNH2SP30 full-bridge motor drivers.
This shield support circuitry that makes it capable of driving a pair of high-current motors!
The VIN and motor out are pitched for our 5mm screw terminals (not included), making it easy to connect larger gauge wires.
Note: When using this board in extreme high-demand applications.
It may be necessary to improve the thermal performance with a heatsink or fan and to solder the wires directly to the board instead of using a screw terminal
(in addition to the myriad other complications present in a high-current system).
VNH2SP30 is a full bridge motor driver intended for a wide range of automotive applications.
The device incorporates a dual monolithic high side driver and two low side switches.
The high side driver switch is designed using the STMicroelectronic’s well-known and proven proprietary VIPower M0 technology.
Which permits efficient integration on the same die of a true Power MOSFET with an intelligent signal/protection circuitary.
The VIN and motor out are pitched for 5mm screw terminals, making it easy to connect larger gauge wires.
INA and INB control the direction of each motor, and the PWM pins turns the motors on or off.
For the VNH2SP30, the current sense (CS) pins will output approximately 0.13 volts per amp of output current.
Voltage Range : 5.5V – 16V
Maximum Current rating: 30A
Practical Continuous Current: 14 A
Current sense output proportional to motor current
MOSFET on-resistance: 19 mΩ (per leg)
Maximum PWM frequency: 20 kHz
Under voltage and Overvoltage shutdown

Step 1: Material Preparation
Picture of Material Preparation
Before getting started, make sure to prepare all of below:
- Arduino Uno Board and USB
- Monster Motor Shield VNH2SP30
- 2 DC Motor 12V
- Jumper Wires / Crocodile Clip
- Adapter / Battery (5.5V – 16V)
Step 2: pin out Details
Hardware Pin out
A0: Enable pin for motor 1
A1: Enable pin for motor 2
A2: Current sensor for motor 1
A3: Current sensor for motor 2
D7: Clockwise (CW) for motor 1
D8: Counter clockwise (CCW) for motor 1
D4: Clockwise (CW) for motor 2
D9: Counter clockwise (CCW) for motor 2
D5: PWM for motor 1
D6: PWM for motor 2
Truth table to make motor to rotate:
STOP: D7 0, D8 0 & D7 1, D7 1
CCW: D7 0, D8 1
CW: D7 1, D8 0
STOP: D4 0, D9 0 & D4 1, D9 1
CCW: D4 0, D9 1
CW: D4 1, D9 0
Step 3: Attach Your Monster Motor Shield VNH2SP30 to Arduino Uno Board
Step 4: Connect DC Motor
Connect Motor 1 to VNH2SP30 Monster Motor Shield VNH2SP30 A1:B1 and Motor 2 to VNH2SP30 Monster Motor Shield A2:B2
Step 5: Power Supply
Connect your Monster Motor Shield VNH2SP30 board to a power supply in range between 5.5V to 16V. We use a 9V power adapter.
Step 6: Assembled Circuit
You will have the whole circuit like this after following previous step. Now, connect your Arduino Uno Board to your computer using the USB.
Step 7: Sample Source Code
This is a sample source code for the circuit, you may download, open and upload it into your Arduino Uno Board.
Make sure to go Tools and select the correct board and port.
Step 8: Serial Monitor
After you have finished compiling the sample source code into your arduino uno board, go to Tools > Serial Monitor and you will get a serial monitor as shown in the picture above.
Step 9: Result
This is the result of this tutorial:
- When user enter number ‘2’, dc motor start to rotate forward and serial monitor will print forward.
- Enter ‘3’, dc motor start to reverse and serial monitor will print reverse.
- Then enter ‘1’, dc motor stop from rotating and serial monitor will print stop.
- When user enter ‘+’, dc motor’s speed increase by 10 and serial monitor will print the motor’s speed.
However, dc motor maximum speed is 255, thus, when user enter ‘++’ more it will still print 255 and never more than 255 (as shown in the pic).
- when user enter ‘-‘, dc motor’s speed decrease by 10 and serial monitor will print the motor’s speed. However, dc motor minimum speed is 0, thus, when user enter ‘–‘ more it will still print 0 and never less than 0 (as shown in the pic).
