3-way PWM Pulse Adjustable Frequency Module for Square Wave Signal Generator Adjustable Duty Ratio Independently

Feature 1 3 way PWM output adjustable frequency 3 way frequency output consistent duty cycle can be adjusted independently suitable for most occasions 2 LCD liquid crystal display frequency and duty cycle very clear very convenient to adjust 3 Wide frequency range high precision 4 Serial communicationDescription 3 way PWM output wide frequency range duty cycle can be adjusted independently in real time Frequency is divided into four ranges automatic switching 1 XXX no decimal point the minimum unit is 1Hz the value range is 1Hz 999Hz 2 X XX decimal point in the hundreds place the minimum unit is 0 01Khz the value range is 1 00Khz 9 99Khz 3 XX X decimal point in the tens place the minimum unit is 0 1Khz the value range is 10 0KHz 99 9KHz 4 X X X decimal point in tens and hundreds minimum unit is 1Khz value range 1KHz 150KHz e g frequency display 100 means PWM outputs 100Hz pulse 1 01 means PWM outputs 1 01K pulse 54 1 means PWM outputs 54 1KHz pulse 1 2 4 means PWM outputs 124KHz pulse duty cycle value range 0 100 where 100 is represented by A0 All setting parameters are saved when power is off Parameter setting The module has 8 independent buttons for setting frequency and duty cycle supporting short press increase or decrease by one unit and long press quick increase or decrease which is very simple After setting the parameters they are automatically saved and will not be lost when power is off The 3 way duty cyc
