- Forward and Reverse Control: The motor requires a complete stop before switching between forward and reverse rotation. Changing directions while the motor is running can damage the circuit board. - External Steering Capability: After removing the short circuit cap, an external steering switch can be connected for enhanced operational flexibility. - Speed Adjustment Options: - Utilize an external 5V, GND potentiometer with a resistance of 10K-100K ohm to fine-tune speed. - Alternatively, apply an external analog input (0-5V) while ensuring a connection to GND on the board. - PWM Signal Input: - Input an external PWM signal with an amplitude of 5V. - Recommended PWM frequency ranges from 1KHz to 10KHz for optimal performance. - Power Supply Compatibility: The motherboard is equipped with a built-in 5V power supply. An external power source can be connected, provided that the current does not exceed 10 mA. Applications: 1. Robotics: Ideal for controlling motors in robotic applications, enabling precise movement in various directions. 2. Automation Systems: Perfect for use in automated machinery where speed and direction control are crucial. 3. Model Vehicles: Suitable for hobbyists building remote-controlled cars or boats requiring variable speed and directional control. This product ensures reliable performance while offering flexibility and compatibility for various applications.
