Adjustable PWM Signal Generator DC Motor Speed Controller(PCB)

1. Working voltage: 3.3-30V
2. Frequency range: normal mode 1Hz-150KHz, fine mode 1Hz-15KHz
3. Signal load capacity: the output current can be around 5-30mA
4. Output amplitude: PWM amplitude is equal to supply voltage
5. Suitable for opening size: about 7.4x3.95cm
6. Weight: about 42 grams
7. Appearance size: about 7.1x3.9x2.5cm

Scope of application:
1. Used as a square wave signal generator to generate square wave signals for experimental development
2. Used to generate the square wave signal to control the motor driver
3. Generate adjustable pulses for MCU use
4. Generate adjustable pulses and control related circuits (applications such as PWM dimming and speed regulation)

Features:
1. Dual mode, duty cycle step 0.1% in fine mode
2. LCD liquid crystal display frequency and duty cycle, very clear, using coded potentiometer to adjust, very convenient, PWM output can set frequency and duty cycle separately
3. With locking function to prevent misoperation
4. Wide frequency range and high accuracy
5. Small mouth communication
