xcluma Signal Generator 3.3V-30V PWM Pulse Frequency Duty Cycle Adjustable Module 1Hz to 150Khz LCD Display PWM Signal Generator Module

1. With LCD LCD display frequency and duty cycle, it is very clear, PWM output can set frequency and duty cycle separately; 2. Wide frequency range and high precision; 3. Serial communication PWM output, you can set the frequency and duty cycle separately; The frequency is divided into four ranges and is automatically switched: 1. XXX ( no decimal point ) : The minimum unit is 1Hz , and the value range is 1Hz~999Hz ; 2. The minimum unit of X.XX (the decimal point is in the hundred digits) 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. XXX ( decimal point in ten and Second, the parameter settings The module has 4 independent buttons for setting the frequency and duty cycle. It supports short press (increase or decrease one unit) and long press (fast increase or decrease). It is very simple. The parameters are automatically saved after setting. Lost. Third, the module parameters: 1. Working voltage: 3.3~30V ; 2. Frequency range: 1Hz~150KHz ; 3. Frequency accuracy: the accuracy in each range is about 2% ; 4. Signal load capacity: the output current can application: 1. Used as a square wave signal generator to generate a square wave signal for experimental development; 2. Used to generate a square wave signal that controls the motor driver; 3. Generate adjustable pulses for use by the MCU ; 4. Generate adjustable pulses and control related circuits ( applications such as PWM dimming speed regulation). (microcontroller TTL level communication) Communication standard : 9600 bps data bits : 8 stop bits : 1 check digit : none flow control : none 1, set the frequency of the PWM “F101”: Set the frequency to 101 HZ (001~999) “F1.05”: Set the frequency to 1.05 KHZ (1.00~9.99) “ F10.5 ”: Set the frequency to 10.5KHZ (10.0~99.9) “F1.0.5”: Set the frequency to 105KHZ (1.0.0~1.5.0) 2, set the duty cycle of the PWM “DXXX”: Set the duty cycle of PWM to XXX ; (001~100) For
