Features: new and DFN packagings technology BLDC wide-voltage 12-30V high-power 200W DC three-phase brushless with Hall controllers. Support 0-5V analog-quantity control,supports PWM to 0-5V control. Only suitable for DC controller with an electrical angle of 120 degrees Brushed with Hall motor. When the external PWM signal is input, the amplitude is 5V, and the recommend PWM frequency is 1K-10KHz. For analog-input, you can use the on-board 5V, Gxternal potentiometer (resistance 10K-100K) to adjust the speed, or you can input (0-5V) analog-externally, but it need to be connect to the on-board.
