XY-PWM1 LCD Display PWM Signal Generator Module 1Hz-150KHz

The XY-PWM1 is a versatile and highly precise PWM signal generator module featuring a clear, high-contrast LCD display. Designed for engineers and makers, this module generates accurate square and rectangular wave signals with an adjustable frequency from 1Hz to 150KHz and a duty cycle from 0% to 100%. It is an essential, reliable tool for equipment testing, motor speed control, dimmer circuits, and hardware debugging.

With its professional panel-mount design and intuitive rotary encoder knob, this module is perfect for integrating into custom control panels, test benches, or DIY electronics projects. It supports dual operating modes—Normal and Fine—allowing for duty cycle adjustments with an accuracy of up to 0.1%. Compatible with a wide range of systems, it operates on a 3.3V to 30V DC input and even features UART support, allowing you to read and set parameters dynamically via an external microcontroller like Arduino, Raspberry Pi, or ESP32.

Features:

• Dual Operating Modes: Features a Normal mode (1% duty cycle steps) and a Fine mode (0.1% steps) for highly precise control.
• Wide Frequency Range: Easily adjustable from 1Hz up to 150KHz to suit various testing and driving applications.
• LCD Display: A clear backlit LCD screen simultaneously displays the current frequency and duty cycle for easy monitoring.
• Rotary Encoder: The high-quality rotary knob ensures accurate parameter adjustments and prevents accidental value changes compared to standard potentiometers.
• Serial Communication: Built-in UART support allows for remote configuration and data reading via a microcontroller.
• Wide Operating Voltage: Supports an input voltage range of 3.3V to 30V DC, making it adaptable to most logic and power systems.
