There are many more driver available at robu.in with these features but they as little costlier as compared to these drivers. Whereas L298N Motor Drivers has the advantage of higher output current up to 2A which suitable for high torque and high RPM motors like Johnson motors and DC Geared motorsĪlthough these drivers are very popular in Makers community, it has some limitations like no short circuit, reverse polarity and overheats protection.
L293D is suitable for small current drawing motors like BO motor, DC geared motor up to 500 RPM and small stepper motor which takes less current than 600mA at their highest torque rating. EMF is provided internally in L293D but must be provided externally in L298. Hence, the heat sink is provided in L298 motor drivers. As L293 output current for each channel is 650mA whereas it is 2A for L298. L293 is quadruple motor driver uses half-H driver while L298 is dual full-H driver, i.e, in L293 all four input-output lines are independent while in L298, a half H driver cannot be used independently, only full H driver has to be used. 600mA Current can be drawn through both channels of L293D whereas L298 can draw up to 2A from both channels. L293D Motor Drivers Operates 4.5V to 36V whereas L298N can be Operates up to 46V. In this way, you can control the speed of the motors by changing the direction of the motors, the PWM A and PWM B fill ratios by making the DIR A and DIR B pins HIGH or LOW. You can use 2 brush DC motors by connecting them to the Motor A and Motor B terminals on the card. These channels can be driven separately using 2 separate DC motors or 1 unipolar or bipolar stepper motor. A total of 4 pins are used by the shield. Each of these channels is controlled by 2 arduino pines. The motor has two independent conduits named shield A and B. Current per 2A channel (with external supply) Engine Controller L298P, 2 DC motors or 1 step motor drive. In this way the driver card will be upgraded to prevent short circuit. 
Important Note: Stackable headers that are shipped inside the product must be installed on the driver card so that the motor terminal on the drive and the Arduino Usb socket are not short-circuited. The buzzer on the card can be used to signal the desired situation. There are also 6 connectors on the card that are connected to Arduino analog pins for rapid prototyping. You can control the speed and direction of the motors independently of each other. It can drive two separate 2A DC motors or one 2A stepper motor. Motors velocity and directions can be controlled separately. It can drive two seperate 2A DC motors or 1 2A step motor. Arduino SMD L298 Dual Motor Driver Shield infoĪrduino Motor Shield L298 is a full-bridge motor driver based on a motor drive integration. Motor Shield is based on L298 motor driver integrated circuit, a full- bridge motor driver.
