Large Current Dual Dc Motor Driver  using ST STMicroelectronics outstanding high-power motor driver chip dedicated L298N, direct drive DC motors, two-phase, four-phase stepper motor drive current up to 2A, motor output using eight-speed Schott group as a protective diode. The circuit line wiring reasonable mount components are used in films, laminated design can be directly plugged into the use of Aduino, reducing the technical difficulty of the user and the drive motor.
