Application: This stepper motor driver uses a large-capacity filter and a flux protection diode for stability. It is normally used to drive stepper motors in smart cars or robots. High efficiency: The driver board delivers strong driving capability, operates at low temperature, and features strong anti-interference performance. The dual-channel H-bridge drive mode provides higher operating efficiency. Dual-channel driver: H-bridge dual-channel type driver. Operating voltage is 5V to 35V, current up to 2A. It can drive a 2-phase stepper motor, one 4-phase stepper motor, or two DC motors. Good heat dissipation: On-board large heat sink for better cooling. Uses large-capacity filters and diode capacitors with freewheel protection function to increase reliability. Applications and use scenarios: - Drive two-phase or four-phase stepper motors in smart cars or robotics for precise positioning and control. - Power a small automation setup requiring one 4-phase stepper motor or two DC motors. - Use in hobby CNC, 3D printer axis control, or other compact automation projects that need reliable dual-channel motor drive and effective heat management.
