L298N Motor Driver Module for Arduino

Key Specifications:

  • Driver Chip: L298N Dual H-Bridge
  • Motor Voltage (VMS): 5V – 35V (or up to 46V in some cases)
  • Output Current: Up to 2A per channel, 4A total
  • Logic Voltage: 5V (for control signals, typically from Arduino)
  • Max Power: ~20W – 25W
  • Control: 4 input modes (2/4 phase for stepper, PWM for speed)
  • Protection: Thermal shutdown, inductive load diodes
  • Indicators: Power LEDs, Heatsink

Pin Functions:

  • ENA/ENB: Enable pins for PWM speed control (Motor A/B).
  • IN1/IN2, IN3/IN4: Input pins for motor direction control.
  • OUT1/OUT2, OUT3/OUT4: Motor output terminals.
  • +12V (or VCC): Motor power input (5V-35V).
  • +5V: 5V output (if jumper is on) or input (if jumper removed).

Important Notes:

  • Powering: Use a separate power supply for motors (5V-35V) and a separate 5V supply or the onboard regulator for logic (Arduino).

Jumper: Remove the 5V jumper if your motor supply is >12V and power the logic separately; keep it on if <=12V to use the onboard 7805 regulator.
