If you downloaded the .RAR file (common for the Engineering Projects and Google Drive versions), you will need to extract its contents. Right‑click the file and choose “Extract Here” or use a tool like WinRAR or 7‑Zip. You should see and L298MotorDriverTEP.IDX . Do not rename these files—Proteus expects specific naming conventions.
This indicates that the .LIB or .IDX files were placed in the wrong folder path, or Proteus was not restarted. Verify the file path matches your specific Proteus version exactly.

: Use logic levels (HIGH/LOW) on IN1/IN2 for Motor A and IN3/IN4 for Motor B to toggle between clockwise and counter-clockwise rotation.
Before diving into the library download and installation, it's useful to understand the component you're working with. The L298 is a high-voltage, high-current dual full-bridge driver designed to drive inductive loads such as relays, solenoids, DC and stepping motors. It can handle up to 46V and 2A per channel, making it suitable for many small to medium robotics projects. The L298 has four input pins (IN1, IN2, IN3, IN4) that determine the direction of each motor, and two enable pins (ENA, ENB) that can be used for PWM speed control. If you downloaded the
Before diving into the library itself, it helps to understand exactly what you’re working with. The L298 is a dual full‑bridge driver IC designed to drive inductive loads like DC motors and stepper motors. It can supply up to 2A of current per channel (with peaks up to 4A) and handle voltages as high as 50V, making it suitable for small robotics projects as well as more demanding motor‑control tasks. Unlike smaller drivers like the L293D, the L298 offers higher output current, built‑in thermal shutdown, and the ability to drive two DC motors simultaneously. These features make it a favorite in projects ranging from line‑following robots to CNC machines and electric vehicle prototypes.
To ensure your simulation mirrors your physical hardware setups accurately, you can review the manufacturer's official electrical parameters in the STMicroelectronics L298 Datasheet. Do not rename these files—Proteus expects specific naming
Proteus does not include a pre-assembled L298N breakout board module in its default component library. Follow these steps to download and install it manually:
Because Proteus does not natively feature the breakout board variant of the L298N, several engineering communities have developed custom simulation models. The most reliable repositories include:
Relaunch Proteus as an Administrator to ensure system-level permissions update correctly. Method 2: For Proteus 7 Professional Copy the downloaded .LIB and .IDX files.
