LKV-HM3.0Double H-bridge DC motor drive boardUsing ST''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s L298N typical dual H-bridge DC motor driver chip, it can be used to drive a DC motor or a bipolar stepper motor. This driver board is small in size, light in weight, and has a strong drive capacity: 2A peak current and 46V Peak voltage; external freewheeling diode can prevent the back electromotive force of the motor coil from damaging the chip when the power is cut off; although the chip has an automatic shutdown function when the chip is overheated, the installation of a heat sink reduces the chip temperature and makes the driving performance more stable; the board is equipped with 2 A current feedback detection interface, internal logic power selection terminal, 4 pull-up resistor selection terminals, 2 DC motor interfaces and four-wire two-phase stepper motor interface, control motor direction indicator, 4 standard fixed mounting holes. This drive board is suitable for intelligent program-controlled cars, wheeled robots, etc. It can be used with various controllers to help you realize your dream of DIY robots.
