The L298 (most commonly deployed on the L298N module board) is a dual full-bridge motor driver designed to handle high voltage and high current inductive loads. It acts as a high-power synchronous interface between low-power microcontrollers (like Arduino, Raspberry Pi, or ESP32) and electric motors that demand far more operating current

Description

  • Power Terminals:

    • 12V / VS: Connects to your external motor power supply (typically 5V–35V).

    • GND: Common ground shared between your power source and your microcontroller.

    • 5V / VSS: Serves as a 5V logic input if your power supply is over 12V (and the 5V regulator jumper is removed), or acts as a 5V power output to your microcontroller if your motor supply is under 12V.

  • Control Input Pins:

    • ENA & ENB: Enable pins for Motor A and Motor B. Removing the jumper cap and applying a PWM signal allows fine speed control.

    • IN1 & IN2: Digital direction control inputs for Motor A.

    • IN3 & IN4: Digital direction control inputs for Motor B.

  • Motor Output Pins:

    • OUT1 & OUT2: Output terminals wired straight to the leads of Motor A.

    • OUT3 & OUT4: Output terminals wired straight to the leads of Motor B.

    • Important Usage Note: Because the L298N relies on older BJT transistor architecture, it suffers from a noticeable internal voltage drop (roughly 1.5V to 2V). This creates significant internal heat under heavy loads, which is why standard modules ship with a large pre-installed aluminum heatsink.
