XY-PWM1 PWM Signal Generator, 1Hz-150KHz Adjustable Pulse Frequency Duty Cycle Square Wave Rectangular Wave Signal Generator Module LCD Display DC 3.3V-30V
Limited time offer, ends 07/30 By TechCore Supply
- The frequency range is 1Hz-150KHz, supporting normal mode (1Hz-150KHz, duty cycle 1% step) and precision mode (1Hz-15KHz, duty cycle 0.1% step), with a frequency accuracy of ± 2%, meeting the accuracy requirements of different scenarios.
- Duty cycle adjustable continuously from 0.00% to 100%, with knob locking function to prevent accidental contact; Can set the upper and lower limits of duty cycle, suitable for scenarios such as motor speed regulation, LED dimming, valve control, etc.
- The working voltage is DC 3.3V-30V, the PWM output amplitude is equal to the input voltage, and the load current is 5-30mA. It supports saving parameters during power failure and does not require repeated settings during restart.
- Equipped with backlit LCD screen, real-time display of frequency and duty cycle; Encoding knob+button combination, short press fine adjustment, long press fast adjustment, supports UART serial communication, can be remotely controlled.

XY-PWM1 is a high-precision PWM signal generator module designed for adjustable square/rectangular wave output. It features a wide frequency range of 1Hz to 150KHz and a 0.00%-100% continuously adjustable duty cycle, providing reliable pulse signals for electronic development, motor control, and circuit testing.
Dual Working Modes for Versatility
- Normal Mode: 1Hz-150KHz frequency range, 1% duty cycle step, ideal for general-purpose applications.
- Precise Mode: 1Hz-15KHz frequency range, 0.1% duty cycle step, perfect for high-accuracy scenarios.
Stable Performance & Easy Operation
Operating on DC 3.3V-30V wide voltage input, the module delivers PWM output amplitude equal to the supply voltage with 5-30mA load capacity. The LCD screen with backlight clearly displays real-time frequency and duty cycle values. The combination of an encoder knob and buttons allows for easy adjustmentshort press for fine-tuning, long press for fast adjustment. All settings are power-down saved to avoid repeated configuration.
