DescriptionDescription:3-way PWM output, wide frequency range, duty cycle can be adjusted independently and in real time.Frequency is divided into four ranges, automatic switching:#The smallest unit is 1Hz, the range of values is 1Hz ~ 999Hz;#The duty cycle ranges from 0% to 100%, of which 100% is represented by %.#All setting parameters,#power down save.Features:1. 3-way PWM output, frequency adjustable, 3-way frequency output consistent, duty cycle can be independently adjusted, suitable for most occasions;2. LCD LCD display frequency and duty cycle, very clear, easy to adjust.3. Wide frequency range and high accuracy;4. Serial CommunicationUsed as a square wave signal generator to generate square wave signals for experimental development and use;Square wave signal used to control motor driver;Generate adjustable pulses for MCU use.Generate adjustable pulses and control related circuits (PWM dimming and speed regulating applications).The module has 8 independent keys to set the frequency and duty cycle. It supports short press (increase or decrease a unit) and long press (increase or decrease quickly). It is very simple. After setting parameters, it can save automatically without losing power.3-way duty cycle button can be pressed at the same time, real-time adjustment, LCD display is the last pressed button duty cycle, real-time performance is very strong, can be used as a simple scan of several ways duty cycle.Specification:Working voltage: 3.3-30VFrequency range: 1Hz~150KHzFrequency accuracy: the accuracy in each range is about 2%Signal load capacity: the output current can be about 5-30 maOutput amplitude: PWM amplitude is equal to supply voltageAmbient temperature: – 20°~ 70°CPackage included:1 Controller Module
