Double BTS7960 43A H-Bridge High-Power Stepper Motor Driver Module

Product Description

The BTS7960 43A High-Power Motor Driver is an industrial-grade H-Bridge module designed for driving high-current DC motors with extreme precision and safety. Unlike standard hobbyist drivers, this module utilizes two BTS7960 chips in a "Half-Bridge" configuration to form a complete H-Bridge capable of handling up to 43A of peak current. It is the premier choice for heavy-duty robotics, electric vehicles, and high-torque automation projects. The board features a massive integrated aluminum heatsink to dissipate heat during high-load operations and includes a 74AHC244 isolation chip to shield your sensitive microcontroller (like an Arduino or Raspberry Pi) from the high-voltage noise of the motor circuit.

Key Features

• Extreme Current Capacity: Capable of driving motors that require up to 43A peak, making it suitable for large RS-775 or wheelchair motors.

• Microcontroller Isolation: Features an onboard buffer IC to isolate the logic side from the power side, preventing "back-feed" damage to your controller.

• Active Status Feedback: Provides a diagnostic "Is" pin that outputs a current-proportional signal, allowing for real-time load monitoring and stall detection.

• High-Speed PWM: Supports high-frequency PWM signals for smooth, silent speed control and immediate directional braking.

• Robust Thermal Design: The chips are directly bonded to a large-area finned heatsink, ensuring stable performance even at continuous high-amperage draws.

Technical Details

• Logic Pins: RPWM (Forward), LPWM (Reverse), R_EN (Forward Enable), L_EN (Reverse Enable).

• Diagnostic Pins: R_IS and L_IS (Over-current and thermal alarm outputs).

• Mounting: Four 3mm mounting holes for secure chassis attachment.
