The L298N Dual-Channel H-Bridge Motor Driver is the "gold standard" for high-power motor control in the DIY electronics world. At Electrapac, we recommend this module for hobbyists who need to drive larger DC motors or a stepper motor that requires more current than a standard shield can provide.

Product Overview

The L298N is a high-voltage, high-current dual full-bridge driver designed to accept standard TTL logic levels. It can drive two DC motors or one 4-wire two-phase stepper motor. Built around a heavy-duty heatsink, this module is perfect for 2WD and 4WD robot platforms, automated gates, and any project requiring bi-directional control of motors drawing up to 2A each.

Key Features for Electrapac Customers

• Dual H-Bridge Architecture: Allows you to control the direction and speed (via PWM) of two DC motors independently.

• Integrated 5V Regulator: Features an onboard 78M05 regulator. If your motor power is between 7V and 12V, the module can provide a steady 5V output to power your Arduino or sensors.

• Large Heat Sink: The oversized aluminum heatsink ensures the chip stays cool even during sustained high-torque operations, preventing thermal shutdown.

• High-Quality Capacitors: Equipped with large-capacity filter capacitors and freewheeling diodes to protect against back-EMF and inductive spikes.

• Screw Terminal Interface: Easy-to-use terminals for motor outputs and power inputs, eliminating the need for soldering during the prototyping phase.

Understanding the Connectors

To get the most out of your purchase from  www.electrapac.com, here is the pin breakdown:

• VCC: Motor power (7V to 35V).

• GND: Common ground (must be connected to the Arduino GND).

• 5V: 5V Input/Output. (If the 12V jumper is in place, this acts as an output to power your Arduino).

• IN1 & IN2: Controls Motor A direction.

• IN3 & IN4: Controls Motor B direction.

• ENA & ENB: Speed control pins (Remove the jumper to use PWM for variable speed).

Primary Applications

• High-Torque Robots: Driving larger gear motors for obstacle-avoiding or line-following robots.

• Stepper Motor Control: Perfect for driving NEMA 17 steppers in small CNC or automation projects.

• Remote Controlled Vehicles: Building custom RC cars that require 12V power systems.

• Smart Home Hardware: Automating motorized curtains, locks, or conveyor belts.
