Dual H Bridge DC Stepper Motor Drive Controller Board Module arduino L298N
Double H Bridge Motor Driver Module
Drived by H bridge
2A (MAX single bridge)
1.Using L298N made by ST company as the control chip,the module has such characteristics as strong driving
ability,low calorific value and strong anti-interference ability.
2.This module can use built-in 78M05 for electric work via a driving power supply part.But to avoid the damage
of the voltage stabilizing chip,please use an external 5V logic supply when using more than 12V driving voltage.
3.Using large capacity filter capacitor,this module can follow current to protect diodes,and improve the
L298N is a kind of high voltage,high current motor driver chip produced by ST company.Having 15 pins as package,
this chip has such features as high working voltage(maximum voltage up to 46V),large output current(instantaneous
peak current up to 3A,continuous working current 2A) and 25W of rated power.Two built-in H birdge high voltage and
large current full bridge drivers can be used to drive the DC motor and stepper motor,relay coil and so on.Using standard
logic level signal control,it has two enable control ends.It permits or prohibites device having a logic power supply imput
without the impact of input signal,which enables the internal logic circuit part works at low voltage.The chip can connects
to external detecting resistor to give the variations to the control circuit.Using L298N chip to drive the motor,this chip can
drive a stepping motor or four phase stepping motor,and two DC motors as well.
This module is integrated with a built-in 5V power.When the drive voltage is 7V-35V,
it can enable the onboard 5V logic power supply;afterthe power supply,don't input
voltage in the interface+5V power supply,but you can lead the 5V for external use.
when ENA enable IN1 IN2 control OUT1 OUT2
when ENB enable IN3 IN4 control OUT3 OUT4
1 Driving stepper motor
The connection of driving a common 4 line 2 phase electric motor is shown in below figure
after enable ENA ENB
Input the following driving timing from IN1-IN4?then the speed and direction of the stepper
motor can be controlled
2 Driving DC motor
Because the module is drived by double H bridge,it can drive two motors simultaneously.
The connecting method is shown inbelow figure
after enable ENA ENB
You can imput the speed and direction of PWM signal drive motor 1 from IN1 IN2
You can imput the speed and direction of PWM signal drive motor 2 from IN1 IN2
The signal is shown in the figure
