1HZ~150KHZ Signal Generator Digital Display PWM Pulse Frequency Duty Ratio Adjustable Square Wave Rectangular Signal Generator

The frequency is divided into four ranges and automatically switched: 1.XXX (no decimal point): the minimum unit is 1 Hz, and the value ranges from 1 Hz to 999 Hz; 2.X.XX (the decimal point is in the hundredth place) The minimum unit is 0.01Khz, and the value range is 1.00Khz~9.99Khz; 3.XX.X (decimal point is ten): the minimum unit is 0.1Khz; the value range is 10.0KHz~99.9KHz 4.X.X.X (decimal point in ten and hundred): the minimum unit is 1Khz; the value range is 1KHz~150KHz E.g. Frequency display: 100 means PWM output 100Hz pulse; 1.01 indicates that the PWM outputs a pulse of 1.01K; 54.1 indicates that the PWM outputs a pulse of 54.1 kHz; 1.2.4 indicates that the PWM output is a pulse of 124KHz; All setting parameters are saved after power down. Parameter? Working voltage: 3.3~30V; Frequency range: normal mode 1Hz~150KHz; fine mode 1HZ~15KHZ; Frequency accuracy: the accuracy in each range is about 2%; Signal load capacity: the output current can be around 5~30ma; Output amplitude: The PWM amplitude is equal to the supply voltage; Ambient temperature: -20~+70°C. Weight: 42g Application: Used as a square wave signal generator to generate a square wave signal for experimental development; Used to generate a square wave signal that controls the motor driver; Generate adjustable pulses for use by the MCU; Generate adjustable pulses, control related circuits (PWM dimming speed adjustment applications, etc.)
