Use ENA and ENB with PWM signals from your microcontroller to control speed.Include decoupling capacitors and ensure the power supply can handle motor stall currents and peaks.Recommended Wiring NotesUse short, thick wires for motor power to reduce voltage drop.Place capacitors near the motor supply terminals to reduce noise and voltage spikes.Consider adding external flyback diodes or use motors with suppression to protect logic from noise.Performance TipsUse a power supply rated above the motor stall current and provide headroom for peak draws.Improve cooling with additional heat sinks or fans for prolonged high-current operation.Test PWM frequency and duty cycle to find balance between smooth motor response and heat generation.Ensure proper grounding between the driver and microcontroller to avoid signal errors.What is Included1x L298N Motor Driver Module Dual H-Bridge 3ADocumentation and basic wiring diagram (digital download or printed insert)Order the L298N Motor Driver Module Dual H-Bridge 3ABring reliable, cost-effective motor control to your next project.
