Clear and precise display for easy configuration The square signal wave generator provides a clear LCD display that shows both frequency and duty cycle settings. The PWM output allows independent adjustment of frequency and duty cycle, delivering precise control for your projects. The display is easy to read and provides realtime feedback for accurate adjustments. Wide range with dependable accuracy Frequency range: 1 Hz to 150 kHz with accuracy within 2% in each range. Whether you need lowfrequency signals for motor control or frequency pulses for circuit testing, this module delivers reliable performance across applications. Versatile applications for development and testing Serves as a square wave signal generator for experimental development, motor driver control, and adjustable pulse generation for MCUs. Its use cases include PWM dimming, speed regulation, and controlling related circuits. Intuitive, reliable controls Four independent buttons allow easy setting of frequency and duty cycle. Short presses adjust values by one unit; long presses enable rapid changes. The design is intuitive, and all parameters are automatically saved after setting. Use scenarios Motor control: generate PWM signals to drive motor drivers for precise speed and torque control. MCU and electronics testing: produce precise square waves or PWM signals to validate timing and logic in digital circuits. PWM dimming and speed regulation: adjust duty cycle for lighting control or mechanical speed regulation in various systems.
