DollaTek 1Hz 150Khz Signal Generator module adjustable PWM pulse frequency duty cycle square wave rectangular

LCD liquid crystal display frequency and duty cycle, very clear, PWM output can be set separately frequency and duty cycle. The module has four independent keys, used to set the frequency and duty cycle, support short press (increase or decrease a unit) and long press (fast increase or decrease), very simple, set the parameters automatically save, power failure Lost. Used as a square wave signal generator, generate square wave signal for experimental development and use. Used to generate a square wave signal that controls the motor driver; Generate adjustable pulse for MCU use. Working voltage: 3.3 ~ 30V; Frequency range: 1Hz ~ 150KHz; Frequency accuracy: the accuracy in each range is about 2%;
