Board 5pin Hall interface, used to access the motor Hall signal.Onboard burning interface for updating the burning program. The module is bare by default. If the motor is driven below 5A current, it does not need to be forced to dissipate heat, but only needs to normal ventilation. If current exceeds 5A, it must be forced to dissipate heat. Features: the working voltage is 6-80V, and the anti-reverse connection protection is supported, and the module not be damaged due to the power line reverse connection. Onboard LED indicator for standby, working, error and other states.Onboard potentiometer (0.5~5V), PWM speed control interface (frequency 1~20KHz), duty cycle 10~100%. Onboard FG speed feedback interface, calculation speed RPM=FG frequency Hzx60/pole number.Onboard CW/CCW steering interface, suspended for clockwise CW, short-circuited GND for counterclockwise CCW steering.Onboard UART serial port. Users can control the module through the serial port protocol., Weight: 0.1322773572 Pounds, Manufacturer: puhae
