Onboard LED indicator shows system state at a glance, including standby, operating, and error conditions. Power and control Onboard potentiometer: 0.5 to 5 V input for intuitive manual speed adjustment. PWM speed control interface: frequency 1 to 20 kHz for smooth motor control. Duty cycle range: 10% to 100% for flexible speed and torque settings. Motor sensor interface 5pin Hall interface: access to the motor Hall signal for precise feedback or commutation. Onboard burning interface: used to update the firmware or burn the program into the module. Construction and cooling The module ships bare by default; install into your system as needed. Cooling guidance: if the motor current stays below 5 A, no forced cooling is required beyond normal ventilation. If current exceeds 5 A, active cooling or heat dissipation is required. Electrical and protection specifications Working voltage: 6 to 80 V. Antireverse connection protection: the module is protected against reverse polarity power connections, preventing damage. Benefits and practical advantages Clear status visibility with a dedicated LED indicator. Flexible speed control via analog (0.5–5 V) input and PWM, suitable for precise motor tuning. Hall sensor compatibility for motors with Hall feedback, enabling accurate speed/position sensing. Easy firmware upgrades with the builtin burning interface. Robust reversepolarity protection to enhance reliability in harsh or evolving setups. Compatibility and performance notes Designed for DC motors operating within 6–80 V. Suitable for applications requiring variable speed control, motor feedback, and safe operation under reverse polarity conditions. Bare module format allows direct integration into custom enclosures, panels, or compact robotics builds. Use scenarios Robotics projects: integrate with a Hallsensor DC motor, use the potentiometer for quick manual tuning and the Hall interface for feedbackbased control, with firmware updates via the burning interface. Automated small conveyors or gantries: maintain smooth and adjustable motor speed using the 0.5–5 V control signal and 1–20 kHz PWM, while monitoring status via the LED indicator. Model and hobby systems: power a hobby motor from 6–80 V, adjust speed on the fly with the potentiometer, and protect against reverse wiring during field work.
