The L298N driver module, using ST' L298N chip, can directly drive two 3-30V DC motor, and provide a 5V output interface, power for 5V single-chip circuitry , support 3.3VMCU control. you can easily control the DC motor speed and direction, also control the 2-phase stepper motor. It is essential for smart car.
SPECYFIKACJA TECHNICZNA

SPOSÓB STEROWANIA
- ENA and ENB enable the H-bridges A and B, respectively
- Jumpers U1-U4 allow for easily tying IN1-IN4 to 5V. To allow for full control of the H-Bridges remove these jumpers. IN1 and IN2 control bridge A; IN3 and IN4, bridge B. The following example specifies control of bridge A using IN1 and IN2, but the same logic applies using IN3 and IN4 to control bridge B
- To move the motor forward: IN1=H, IN2=L, ENA=H
- To move the motor backwards: IN1=L, IN2=H, ENA=H
- To quickly stop the motor: IN1=L, IN2=L, ENA=H OR IN1=H, IN2=H, ENA=H
- To slowly stop the motor (free-run stop): ENA=L (IN1 and IN2 ignored)
- The 5V_EN jumper enables the onboard regulator
- The CSA and CSB pins are the current sense pins for bridge A and bridge B and can be used to sense the motor current. These are also broken out to jumpered headers. If not using current sense leave the pins jumpered to ground
