Monster Moto Shield VNH2SP30 Motor Driver 14A (Peak 30A)

Monster Moto Shield VNH2SP30 Motor Driver 14A is essentially a ramped up version of our Ardumoto motor driver shield. For this Monster Moto Shield, we’ve replaced the L298 H-bridge with a pair of VNH2SP30 full-bridge motor drivers.

We’ve also beefed up the support circuitry so this board is 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.

VNH2SP30 Pin Functions

INA and INB used to control the direction of Motor; whether clockwise or anti clockwise.

PWM pin can be used to control the speed of the rotation of motor and top turn it on or off.

Basically these are the 3 pins you need to drive the motor.

Then we have another pin that can be used to measure the output current. Current Sense (CS) pins will output a voltage proportional to the current drawn (0.13 volts per amp) of output current.

Motor Power Supply – There are two ports where you can provide a voltage to drive the motor.

IC Pwer Supply – There are VCC and Gnd pins where you provide a voltage of 5V for the working of the internal circuitry.

Controlling DC Motor using Arduino and VNH2SP30 Motor Driver

We will now connect Arduino to VNH2SP30 and write a single code to rotate DC motor clock wise and counter clock wise and control their speed using Arduino and VNH2SP30 motor driver.
