1Hz-150KHz PWM Pulse Frequency Duty Cycle Module Adjustable Signal Generator

Operating voltage: 3.3 - 30V; Frequency Range: 1Hz - 150KHz; Frequency accuracy: the accuracy is about 2% in each range. Signal load capacity: output current can be about 5 - 30ma; Output amplitude: the PWM amplitude is equal to the supply voltage. Ambient temperature: -20 - +70 C. Module descriptionPWM output can set the frequency and duty cycle accordingly. The frequency is divided into four areas: automatic switching:1.XXX (without decimal point): the smallest unit is 1Hz, and the value range is 1Hz - 999Hz; Minimum unit2. X.XX (decimal in 100 bits) is 0.01Khz, and the value range is 1.00Khz - 9.99Khz;3.X X.X (decimal in ten places): the smallest unit is 0.1Khz; And the range is 10.0KHz - 99.9KHz.4.X.X.X (decimal in ten bits and 100 bits): the smallest unit is 1Khz; And the range is 1KHz - 150KHz.E.g. Frequency display: 100 indicates 100Hz PWM output pulse; 1.01 represents the 1.01K.54.1 PWM output pulse.1.2.4 indicates the 124KHz PWM output pulse. Duty cycle: 0 - 100%; All settings are saved by power off. Parameter SettingThe module has four independent keys, used to set the frequency and duty cycle, support short press (increase or decrease the unit) and long press (quickly increase or decrease), very simple, set the parameters automatically save, power loss will not be lost. Scope of application:1. It is used as a square wave generator to generate square wave signals for experimental development.2. It is used to generate square wave signals that drive the control motor.3. Generate an adjustable pulse for MCU use;4. Generate adjustable pulses to control the associated circuitry (PWM dimming applications and speed control). Size: 7.8 x 4.2 x 2.6cm/3.07 x 1.65 x 1.02inchNote: Please allow 1-3mm error due to manual measurement. pls make sure you don't mind before you bid.
