L298n Motor Driver Circuit Diagram. It is a high voltage and high current full dual bridge driver designed to accept standard ttl logic level and drive inductive loads such as relays solenoids and dc stepper motor. Pulse width modulation is a means in controlling the duration of an electronic pulse.
Most of the microcontrollers operate on very low voltage 5v and current while the motors require higher voltages and current so the microcontrollers cannot provide them such higher current. This dual bidirectional motor driver is based on the very popular l298 dual h bridge motor driver integrated circuit. L298n h bridge module overview.
L298n dual h bridge motor driver.
The l298n motor driver module is based on the powerful l298n motor driver ic. Using a breakout board is easier for prototyping compared to using the ic. Information about the l298n motor driver. The pin diagram of the l298n motor driver ic is shown in the image below.
