Note: The L298's hard break function is not supported. However yo'll need to supply external 5V to the L298's logic circuit otherwise your motor will not move. Octopart is the world's source for L298N availability, pricing, and technical specs and other electronic parts. If your supply is greater than 12V, remove the jumper to prevent damage to the voltage regulator. Find the best pricing for STMicroelectronics L298N by comparing bulk discounts from 10 distributors.
There is also an onboard 5V regulator - so if you're using between 7 and 12V DC to driver the motors, you can connect the jumper to allow this voltage regulator to supply 5V to your L298's logic circuit.
Check the datasheet of your stepper motor and look for the voltage/current draw of the motor. The RPM is controlled using PWM input to ENA or ENB pins, while of rotation direction is controlled by suppling high and low signal to EN1-EN2 for the first motor or EN3-EN4 for second motor. Control a stepper motor with L298N motor driver and Arduino. The driver can control both motor RPM and direction of rotation. It is a high voltage, high current dual full-bridge driver designed to accept standard TTL logic levels and drive inductive loads such as relays, solenoids, DC. The driver has a nice heatsink to keep the L298N cool and all driver lines are diode protected from back EMF. The board can be used to drive either a single stepper motor, 2 bi directional DC Motors. If you can’t nd the datasheet, you can measure the resistance of one of the.
This dual motor driver is based on the L298N heavy-duty dual H-bridge controller, which can be used to drive two DC motors at up to 2A each, with a voltage between 5 and 35V DC - or one stepper motor or 2 solenoids with ease. The L298 Driver is a high voltage, high current dual ful bridge driver designed to accept standard TTL logic levels and drive inductive loads such relays. The L298N is a dual full-bridge high current motor driver. Stepper Motor with L298N and Arduino Tutorial (4 Examples).
