![]() This 5V will power the logic circuitry of the L298N arduino. Supply 5V Logic: Keep the 5V-EN jumper in place to enable the on-board 5V regulator, which derives 5V from the motor power supply.This voltage is suitable for our NEMA 17 bipolar stepper motor. Connect Power Supply: Use an external 12V power source and connect it to the VS terminal on the L298N module.To wire a Bipolar Stepper Motor to the L298N Module and Arduino, follow these steps: ![]() Wiring a Bipolar Stepper Motor to the L298N Module and Arduino Here are the specifications: Motor output voltageįor more details, please refer below datasheet. The L298N motor driver chip is a popular choice among hobbyists and engineers for its ability to drive motors smoothly and efficiently. Compatibility: It is widely used in robotics, automation, and various projects that involve motor control due to its reliability and performance.Heat Dissipation: The L298N chip is equipped with a heat sink to efficiently manage the generated heat during motor operation.Current Capacity: Each L298N H-bridge can handle a continuous current of up to 2A per coil, providing sufficient power for most arduino stepper motor controller.Supply Voltage Range: The chip operates within a supply voltage range of 5V to 35V, making it suitable for various power sources.Integrated H-Bridge Configuration: The L298N contains two full H-bridges that enable bidirectional control of two DC motors or the precise movement of a single stepper motor arduino. ![]() It plays a vital role in the functionality of stepper motor systems, offering versatility and efficiency in controlling their motion. The H-Bridge allows for precise control over the stepper motor’s movement, enabling applications that require accurate positioning, such as robotics, CNC machines, and 3D printers. To reverse the rotation, the sequence of energizing the coils is altered, leading to the stepper motor turning in the opposite direction. This sequence determines the direction and number of steps the motor takes.įor example, to make the stepper motor rotate in one direction, the H-Bridge energizes the coils in a specific order, causing the motor to move in precise steps. Each pair of switches corresponds to one of the electromagnetic coils within the stepper motor.īy selectively energizing the coils in a specific sequence, the L298N H-Bridge can control the rotation and movement of the stepper motor. It consists of four switches arranged in an “H” configuration, with the stepper motor placed at the center. ![]() Using an H-Bridge to Control a Stepper MotorĪn H-Bridge is a crucial component used to control the movement of a stepper motor.
