Dual H-bridge DC Motor Driver stepping motor driver
Introduction LKV-HM3.0 Dual H-bridge motor driver uses ST typical L298N dual H-bridge motor driver chips to drive DC motors or bipolar stepper motors. Small in size, light in weight and excellent in performance, with peak current up to 2A and voltage up to 46V, this motor driver also has a free-wheeling diode to protect the chip from damage caused by high voltage produced when the power’s turned off. Although the chip will automatically stop working when overheated, the heatsink helps to lower the temperature and achieve more stable capacity.-2 current sense ports-Inner logic power supply selection switch-4 pull up resistor switches-2 DC motor/ 4 pin dual-phase stepper motor output-Motor direction indication LED-4 standard mounting holes This motor driver fits for MCU controlled vehicles, mobile robots, etc., and can be applied with a wide range of controllers; it’s going to be a best option for robot DIY fans.
