Module’s Pinout Configuration
The L298N Motor Driver Module has various pins that serve multiple functions. The IN1 and the IN2 control motor A’s spinning direction, while IN3 and IN4 control motor B’s spinning direction. Both ENA and ENB enable PWM for motors A and B, respectively. The OUT1 and OUT2 pins are the output pins for motor A, whereas OUT3 and OUT4 are the output pins for motor B. The 12V plug is also the input DC, and the 5V pin supplies power to the L298n IC’s switching logic circuitry. Lastly, the GND is the ground pin.
What does L298M entail?
The L298N Motor Driver module incorporates an L298 Motor Driver IC, 78M05 Voltage Regulator, resistors, capacitor, Power LED, and a 5V jumper in an integrated circuit. The 78M05 regulator activates when the jumper is in place, powering the internal circuitry when the supply is ≤12V. The 5V pin functions as an output to power the microcontroller. For supply >12V, the jumper is removed, and a separate 5V input is provided to power the internal circuitry. ENA & ENB control Motor A and Motor B speed, while IN1& IN2 and IN3 & IN4 determine their directions.”
