Frequency Range:
- Normal Mode: 1Hz - 150KHz, duty cycle 000-100, duty cycle step by 1 percent.
- Fine Mode: 1Hz -15KHz, duty cycle 00.0-100, duty cycle step by 0.1 percent.
Frequency Accuracy: The accuracy in each range is about 2 percent.
Signal Load Capacity: The output current can be around 5 - 30mA.
Output Amplitude: PWM amplitude is equal to the supply voltage.
Environmental Temperature: -20 - +70 Degrees Celsius Parameter Settings:
- Adjust the frequency and duty cycle by rotating the potentiometer. Default adjustment of duty cycle, short press to adjust frequency, long press for 2 seconds to lock, long press for 5 seconds to switch modes (normal mode/fine mode). After setting the parameters, they will be automatically saved and will not be lost when powered off. The frequency is divided into 4 ranges and automatically switches:
- XXX (without decimal point): The minimum unit is 1Hz, and the value range is 1Hz - 999Hz
- X.XX (decimal point in hundreds): The minimum unit is 0.01KHz, and the value range is 1.00KHz to 9.99KHz
- XX.X (decimal point in ten places): The minimum unit is 0.1 Khz; and the value range is 10.0KHz - 99.9KHz
- X.X.X (decimal places in tens and hundreds): The minimum unit is 1Khz; and the value range is 1KHz 150KHz
Serial Port Control (microcontroller TTL level communication)
- Communication Standard: 9600bps
- Data Bit: 8
- Stop Bit: 1
- Check Digit: None

- Read Setting Parameters: Send a "Read" String
- Set Successfully and Return: DOWN
- Setting Failed and Returned: FALL
Set the frequency of 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- 15.0)
Set the duty cycle of PWM
- Normal Mode DXXX: Set the PWM duty cycle to XXX; (001-100), for example D050, set the PWM duty cycle to 50 percent.
- Fine Mode DXX.X: Set the PWM duty cycle to XX.X; (00.1-100), for example D20.8, set the PWM duty cycle to 20.8 percent. Place of Application:
- Used as a square wave signal generator to generate square wave signals for experimental development.
- Used to generate square wave signals for controlling the motor driver.
- Generate adjustable pulses for MCU use.
- Generate adjustable pulses and control related circuits (such as PWM dimming speed control applications).
