Usage Tips of double BTS7960 43A High Power Motor Driver Module:
When using the double BTS7960 43A High Power Motor Driver Module, here are some tips to ensure proper usage and maximize its performance:

• Power Supply Voltage: Ensure that the power supply voltage is within the specified operating range mentioned above. Operating the module outside the recommended voltage range may result in damage.
• Motor Specifications: Match the motor specifications with the capabilities of the double BTS7960 module. Check the voltage and current requirements of your DC motors to ensure compatibility.
• Current Sensing: Utilize the current sensing feature to monitor the current flowing through the motors. This can be useful for feedback control and protection purposes.
• Enable/Disable Functionality: Take advantage of the enable/disable function (EN pin) to selectively turn the motor driver on or off. When no force is applied to the motor and you can turn it off, use this to prevent the motors from overheating.
• Heat Dissipation: The double BTS7960 module may generate heat during operation. Provide adequate heat sinking or cooling measures, if necessary, especially if operating at high currents or for extended periods.
• Physical Mounting: Securely mount the module, ensuring good electrical connections and preventing shorts. Pay attention to the module’s physical orientation and mounting holes.
• Testing and Calibration: Before integrating the motor driver into your main system, perform initial testing and calibration to ensure proper functionality. Confirm that the motors respond as expected to control signals.
• Grounding: Properly connect the ground (GND) of the motor driver to the ground of your control circuit. Maintaining a common ground reference is essential for stable operation.
