3pcs Signal Generator PWM Pulse Frequency Duty Cycle Adjustable Module With LCD Display 1Hz-160Khz 4V-30V 5mA-30mA

Instructions: - The single PWM generator has only one set of PWM1 outputs and the frequency and duty cycle are independently adjustable. Two-way complementary PWM has two sets of PWM1 and PWM2 outputs. The two sets of frequencies have the same frequency and their duty cycles are complementary. Specifications: - Adjustable frequency 1-160KHz - Duty cycle 0-100% adjustable - Operating voltage: 4V~30V - Frequency range: 1Hz~160KHz - Frequency accuracy: 2% - Signal load capacity: output current 5~30mA - Output amplitude: The amplitude is equal to the working voltage. - Duty cycle 0~100% adjustable - PWM output, can set the frequency, duty cycle - The frequency is divided into four ranges, automatically switching: 1.XXX (no decimal point): 1Hz~999Hz, unit 1Hz 2.X.XX (decimal point in hundreds): Value is 1.00KHz to 9.99KHz in 0.01KHz 3.XX.X (decimal point in ten digits): The value is 10.0KHz~99.9KHz, the unit is 0.1KHz 4.X.X.X. (full decimal point): Value 100KHz~160KHz, unit 1KHz E.g: 100 represents 100Hz 1.00 means 1.00KHz 10.0 means 10KHz 1.0.0. Represents 100Khz Setting Process: 1. Press the SET button. The frequency parameter flashes. Set the frequency with the UP or DOWN button. 2. Press the SET button. The duty cycle parameter flashes. Set the duty cycle by pressing the UP or DOWN keys. 3. Press the SET button to exit the setting 4. Long press the UP and DOWN keys to quickly increase or decrease 5. The data is automatically memorized and all setting parameters are saved when power is off. Applications: 1. It is used as a square wave signal generator to generate square wave signals for development and use. 2. Used to generate a square wave signal that drives a stepper motor driver. 3. Generate adjustable pulses for use by the MCU. 4. Produce adjustable pulses to control the associated circuitry. Package Included: 3 x Signal Generator Module With LCD Display
