General Interest Hot Products title $16.90 title $1.96 title $1.59 title $1.75 title $3.20 title $5.35 title $7.90 L298N Dual H Bridge DC Stepper Motor Drive Controller Board Module for arduino Basic Attributes Name Double H Bridge Motor Driver Module Working mode Drived by H bridge (double lines) Control chip L298N ? ST ? Logical voltage 5V Driving voltage 5V ? 35V Logical current 0mA-36mA Driving current 2A (MAX single bridge) Storage temperature ? -20 ???? +135 ?? Maximum power 25W weight 30g Periphery dimension 43*43*27mm Product features: 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 reliability 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. Port function? Circuit principle diagram ? 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 Applied cases: 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 Data Download SHIPPING PAYMENT RETURNS FEEDBACK ABOUT US 1)All items will be shipped to your paypal address .Please update your latest address when you check out,and please make sure to provide us with correct,precise and detailed shipping address. 2)Most of the items will be shipped via Hongkong Airmail/Singapore Airmail .To US customers,we will send the package via E-packet . 3)All items will be shipped in 1-2 business days (excluding Sat,Sun & Holiday) after payment received and cleared.
