2 PWM Pulse Frequency Duty Cycle Adjustable Square Rectangular Signal PWM Generator Stepper Motor Driver Module

Module Features 1 Two independent PWM outputs the frequency and duty cycle can be set separately 2 Wide frequency range and high precision 3 Serial communication is possibleModule description Two independent PWM outputs the frequency and duty cycle can be set separately The frequency is divided into three ranges 1 XXX no decimal point The small unit is 1Hz and the value range is 1Hz 999Hz 2 XX X the decimal point is in the tenth place the small unit is 0 1Khz the value range is 0 1KHz 99 9KHz3 X X X three digits have a decimal point the small unit is 1Khz the value range is 1KHz 150KHzFrequency display 100 means PWM output 100Hz pulse 54 1 means that the PWM outputs a 54 1KHz pulse 1 2 4 Indicates that the PWM output 124KHz pulseDuty cycle value range 0 100 The three frequency ranges share a duty cycle and all set parameters are saved after power off Parameter settings The module has 3 buttons Set Up Down 1 By short pressing the Set key switch to display four parameter values ​​ FR1 PWM1 frequency dU1 PWM1 duty cycle FR2 PWM2 frequency dU2 PWM2 duty cycle there will be corresponding parameters before switching Name flashes prompt 2 Directly press Up Down key to modify the current parameter value long press to fast increase or decrease 3 There are 3 frequency values ​​preset for each of the two PWMs In the frequency display interface you can switch by long pressing the SET key once and the duty ratios of the 3 frequencies are t
