XY-LPWM Pulse Frequency Adjustable Module

XY-LPWM Pulse Frequency Adjustable Module is a versatile PWM signal generator designed for applications requiring adjustable frequency and duty cycle. It is widely used for controlling motor speed, dimming LEDs, and signal modulation in embedded systems. The module features an onboard digital display, rotary encoder, and support for both PWM and pulse output modes.

Key Features:

• Wide Frequency Range: Adjustable from 1Hz to 150KHz to suit various control applications.
• Digital Display: 4-digit LED screen shows frequency and duty cycle in real-time.
• Precise Adjustment: Rotary encoder with push-button for intuitive control and quick tuning.
• Dual Mode: Supports both PWM signal and pulse output modes (configurable via menu).
• Memory Function: Remembers last settings after power-off.

Technical Specifications:

• Input Voltage: 3.3V to 30V DC
