DAOKI 5 PCS L298N Motor Drive Controller Board DC Dual H-Bridge Robot Stepper Motor Control and Drives Module for Arduino Smart Car Power UNO MEGA R3 Mega2560

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 input 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.
Description:
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 .
