Adjustable PWM Pulse Frequency Duty Cycle Digital Square Wave Signal Generator
1. Wide frequency adjustable: 1Hz-5MHz ultra wide frequency range
2. Continuous adjustable duty cycle: 0.1% -99.9%, high accuracy
3. Power off automatic saving: parameters are never lost and can be used immediately upon power on
4. High definition digital display: real-time and intuitive display of frequency and duty cycle
5. Compact and portable design: palm sized, suitable for embedded development
Working voltage: 3.3V~30V
Adjustment method: Encoder adjustment
Working current: 20mA
Frequency: 10Hz~150KHZ
Duty cycle: 0%~100% (step 1%)
PWM upper and lower limits: lower limit 0%~70%/upper limit 50%~100%
This module is a low-cost and high-performance PWM pulse signal generator with a wide frequency range, adjustable duty cycle, and power-off storage function. After setting the frequency and duty cycle, it is immediately saved and does not need to be set again the next time it is powered on. It is very convenient, small in size, and has high-definition digital display. Very suitable for some applications that require generating PWM signals and motor speed regulation.
Application areas: motor speed regulation, microcontroller development, pulse generator.
