XY-PWM1 Signal Generator Module Adjustable PWM Pulse Frequency Square Wave

Module description: PWM output can set frequency and duty cycle respectively. Frequency is divided into four areas: automatic switching: 1.XXX (without decimal point): the smallest unit is 1Hz, and the value range is 1Hz~999Hz;The minimum unit of 2.X.XX (decimal point in 100 bits) is 0.01Khz, and the value range is 1.00Khz~9.99Khz; 3.XX.X (decimal point in ten places): the smallest unit is 0.1Khz; and the range is 10.0KHz~99.9KHz. 4.X.X.X (decimal point in ten bits and 100 bits): the smallest unit is 1Khz; and the range is 1KHz~150KHz.E.g. frequency display: 100 indicates PWM output 100Hz pulse;1.01 represents the pulse of PWM output 1.01K.54.1 represents the pulse of PWM output 54.1KHz.1.2.4 indicates the pulse of PWM output 124KHz.Duty cycle:0~100%;All settings are saved by power down. Parameter setting: Module has four independent keys, used to set the frequency and duty cycle, support short press (increase or decrease a unit) and long press (quickly increase or decrease), very sim
