Marvelous L298 Module Schematic

That means there is little headroom to support dropout voltages from 5v regulators.

L298 module schematic. Arduino modules l298n dual h bridge motor controller. Pinouts of l298n motor driver module 2 dc motor output pins 12 volt external motor power supply motor direction control pins in1 in2 in3 in4 motor output enable pins ena enb and a heat sink. An l298n motor driver module consists of an l298n motor driver chip ic.

Quick and simple start guide for using and exploring an l298n dual h bridge motor controller module with an arduino the model in the example i am using is from ebay. We may want to discharge the battery packs to as low as 6 volts before returning the batteries to the charger. The l298 h bridge is base on l298 chip manufacture by st semiconductor.

It is a high voltage a high current dual full bridge driver designed to accept standard ttl logic levels. For more details the datasheet given to the below link. The l298n motor driver ic actually has two input power pins viz.

The l298n motor driver module consists of an l298 ic dual h bridge 5v 78m05 voltage regulator resistors capacitor power led 5v jumper. This allows you to control the speed and direction of two dc motors or control one bipolar stepper motor with ease. From vs pin the h bridge gets its power for driving the motors which can be 5 to 35v.

This module consists of an l298 motor driver ic and a 78m05 5v regulator. There is also an. The l298n motor driver module is powered through 3 pin 3 5mm pitch screw terminals.

Connect the a a b and b wires from the stepper motor to the module connections 1 2 13 and 14 respectively. Then connect the power supply as required to points 4 positive and 5 negative gnd. L298n module can control up to 4 dc motors or 2 dc motors with directional and speed control.
