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

• 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%;
