Integrated 78M05 regulator provides a stable 5V supply for microcontroller boards and stabilizes the module's internal circuits, increasing system stability and reducing powerdesign complexity. L298N Motor Driver Module offers voltage and current driving capabilities, supporting up to 46V input and delivering up to 3A, making it suitable for powering performance motors in applications such as robotics cars. Designed for engineers and hobbyists, the module uses standard control signals that readily interface with microcontrollers and digital circuits, simplifying motor control design. For robotics and automation projects, speed regulation is available via the enable control pin, enabling PWMbased motor speed control by varying the duty cycle of the input signals. Use scenarios Build a small autonomous robotics car: drive DC motors with the L298N while powering your microcontroller from the module's 5V regulator; leverage PWM for speed control. Prototype automation systems or educational robotics kits: use the standard signal interface to connect with common microcontrollers and adjust motor speed via the enable pin. Hobbyist motor control experiments: explore voltage, current motor setups within a single compact module, reducing wiring and design complexity.
