LKV-HM3.0 dual H-bridge DC motor driver board using ST's L298N typical dual H-bridge DC motor driver IC, which can be used to drive DC motors or bipolar stepper motors. This driver board is small, light weight, but with a strong drive capability: 2A peak current and peak voltage of 46V.Although the chip with the automatic shut-off function when it is overheating , but installing the heat sink could make the chip temperature decreases, so that the drive performance is more stable.

Board has two current feedback detection interface to take power within the logic selects the terminal, four pull-up resistor selection terminal, 2-way and four-wire interfaces DC two-phase stepper motor interface, control motor direction indicator, four standard fixed mounting holes. This driver board could be used with smart programmable trolley, wheeled robots and variety of controllers.

Dual H driver module uses ST L298N dual full-bridge driver, an integrated monolithic circuit in a 15- lead Multiwatt and PowerSO20 packages. It is a high voltage, high current dual full-bridge driver designed to accept standard TTL logic levels and drive inductive loads such as relays, solenoids, DC and stepping motors. Two enable inputs are provided to enable or disable the device independently of the input signals. The emitters of the lower transistors of each bridge are connected together,and the corresponding external terminal can be used for the connection of an external sensing resistor. An additional supply input is provided so that the logic works at a lower voltage.
