HW-515 DC 2CH PWM Signal Generator Duty Cycle Pulse Frequency Module Board, 501 Original

HW-515 Micro USB DC 2CH Adjustable PWM Signal Generator Duty Cycle Pulse Frequency Module Board Digital LED Display TubeDescriptions:The frequency is divided into three ranges:XXX (without decimal point): the smallest device is 1 Hz, the range is 1 Hz ~ 999 Hz;XX.X (Decimal point in ten): The minimum block is 0.1 kHz; 0.1 kHz ~ 99.9 kHzXXX (there are Three decimal points): the smallest block is 1 kHz; 1 kHz ~ 150 kHz rangeDisplay frequency, for example:\"100\" means output PWM pulse 100 Hz;\"54.1\" means that the output of the PWM pulse is 54.1 kHz;\"1.2.4\". Indicates that the PWM pulse output is 124 kHzDuty cycle in the range: from 0 to 100;The three-frequency duty cycle is the same, all parameters are non-volatile.Parameter settings:The module has three buttons (set), (up), (down);Press (set) to switch the display with four parameters (FR1: PWM1 frequency; dU1: PWM1 duty cycle; FR2: frequency PWM2; dU2: PWM2 duty cycle), before passing the parameters, there will be a corresponding parameter name flash.Press (up), (down) keys to change the current parameter value (long press can quickly add or subtract quickly).Two PWM each has three preset frequencies, frequency display interface, long press (set) key to switch between three types of frequencies, three kinds of frequency cycle is the same value.
