BTS7960B 43A PWM Stepper Motor Driver H-Bridge

The BTS7960B 43A H-Bridge Motor Driver is built for engineers who can't afford failure. Powered by dual Infineon BTS7960 half-bridge ICs, this module handles peak currents up to 43 A with built-in protection against over-temperature, over-voltage, short-circuit, and shoot-through — all while keeping your microcontroller completely isolated from motor transients. Four wires from any MCU is all it takes. This is the driver serious projects demand.

🔹 Key Applications

• Bidirectional speed control of high-current DC motors in robotics platforms
• CNC machine axis drivers requiring precise PWM speed regulation
• Electric go-kart and small EV motor controllers
• Industrial conveyor belt and actuator drive systems
• Automated sliding-gate and garage-door opener mechanisms
• Winch and hoist motor control in remote-operated vehicles
• Battery-powered UAV ground drive and steering systems

🔹 Why Choose This Module?

1 × BTS7960B H-Bridge Motor Driver Module

🔹 Pro Tip

💡 Add a 100 µF electrolytic capacitor across the motor supply terminals to suppress voltage spikes at commutation. For CNC applications, pair with limit switches and an Arduino Mega for a complete closed-loop axis controller.

⚠️ Note: Always ensure proper heat dissipation and correct voltage configuration before powering connected devices.
