Hw 130 Motor Control Shield For Arduino Datasheet Better Jun 2026

Standard analogWrite() at 490Hz works fine, but the L298N hums. For silent operation, use Timer1 to set PWM to 15–20 kHz (inaudible).

The L293D chip is very forgiving. It has built-in thermal shutdown to prevent it from burning out if it gets too hot and internal diodes to protect the circuit from voltage spikes created by the motors when they stop or reverse. This "bulletproof" design is a safety net for beginners. hw 130 motor control shield for arduino datasheet better
