Wide working voltage and reverse protection Operates from 6 to 80 V and supports antireverse connection protection, preventing damage if the power line is connected incorrectly. Bare module with clear cooling guidance The module ships bare. If the driven motor current stays below 5 A, no forced cooling is required beyond normal ventilation. If current exceeds 5 A, active heat dissipation is needed. Visual and control interfaces for easy operation Onboard LED indicators display standby, operating, error, and other states for quick status checks. Onboard potentiometer provides a 0.5 V to 5 V input for manual control. PWM speed control interface supports a frequency range of 1 kHz to 20 kHz. Duty cycle adjustable from 10% to 100%. Hall feedback and firmware update capabilities 5pin Hall interface allows access to the motor Hall signal for sensor feedback. Onboard interface for firmware burning (updating the program) to keep the system up to date. Clear compatibility and performance notes Suitable for motors that use Hall sensors and require PWM speed control within a 6–80 V supply range. Designed to handle currents with guidance on cooling: under 5 A requires only normal ventilation; above 5 A requires forced cooling. Practical use scenarios 1) DIY robotics and automation projects Drive a BLDC motor with Hall feedback in hobby robots, conveyors, or small automation systems. Use the PWM input to set speed, monitor via the LED indicators, and adjust the voltage within the 6–80 V range. 2) Prototyping and testing with safe operation Use reverseprotection to protect power wiring during testing. Start with currents below 5 A to avoid extra cooling needs, then enable forced cooling for highercurrent tests to maintain reliability. 3) Firmware updates and motor tuning Update device firmware via the onboard burning interface, and finetune speed using the potentiometer and PWM interface while monitoring Hall feedback on the 5pin interface for accurate motor control.
