Onboard LED indicator shows standby, running, error and other states for quick status at a glance. Onboard speed control options include a potentiometer (0.5 to 5 V) and a PWM interface (frequency 1 to 20 kHz) with a duty cycle range of 10% to 100%, enabling precise speed adjustments. Wide operating voltage and protection: works from 6 to 80 V and includes antireverse connection protection, so the module is not damaged by reverse power connection. Interface features: a 5pin Hall interface on the board for accessing the motor Hall signal, and an onboard burning interface for updating firmware/programs. The module ships bare by default. If the motor current is below 5 A, forced heat dissipation is not required beyond normal ventilation; if the current exceeds 5 A, forced cooling is required. Use scenario 1: Ideal for projects requiring control of BLDC motors with Hall sensors in robotics or automation, using either the potentiometer or PWM control for precise speed tuning across a wide voltage range. Use scenario 2: Suitable for hobbyist or small to midscale motor systems that need reliable reversepolarity protection to prevent damage during power setup or wiring mistakes, while enabling safe operation from 6 to 80 V. Use scenario 3: Firmware updates or field upgrades via the onboard burning interface, allowing you to update the control program without external tools.
