AJMRTC 4PCS L298N Dual H-Bridge Motor Driver Module, DC Stepper Motor Controller Board, PWM Speed Control Module for Arduino ESP32 STM32 Robot DIY Project

AJMRTC pack includes 4 pieces of classic L298N motor driver boards, widely used for DC motor and stepper motor control in embedded and robot projects. Adopting dual H-bridge architecture, each module can drive two separate DC motors with independent direction and speed control, or run one bipolar 4-wire stepper motor. It supports PWM speed adjustment, allowing you to precisely tune rotation speed through signal output from main controllers.

The module separates logic power and motor power supply, which effectively reduces motor back EMF interference and protects the main control chip. Power indicator and status LEDs help you quickly check power-on and working status. Reverse polarity protection circuit prevents burnout caused by wrong power wiring. Screw terminal blocks are used for motor and power connection, making wiring firm and convenient without repeated soldering.

It works seamlessly with mainstream microcontrollers such as Arduino, ESP32, STM32 and AVR chips. Common applications include smart cars, robotic arms, tank chassis, conveyor belt models and small automation equipment. The 4-module set is suitable for multi-axis robot builds, group project development or backup spare modules. It is a cost-effective choice for students, electronics hobbyists and maker teams.
