XY-LPWM Signal Generator PWM 1Hz-150Khz 3.3V-30V Pulse Frequency Duty Cycle LCD

High-Precision Wide Frequency Range (1Hz – 150kHz): Synthesizes precise pulse-width modulation signals spanning from 1 Hz up to 150 kHz with four automatically switching decimal-point frequency ranges.

Blue Backlit LCD Screen: Clear, high-contrast LCD screen simultaneously displays frequency and duty cycle values for instant parameter readouts.

Full Duty Cycle Control (0% – 100%): Fine-tune duty cycle percentages with 1% resolution across all operating frequency bands.

TTL Serial Communication (UART): Built-in serial port allows remote parameter modification, query, and output switching directly via microcontroller or PC (TXD/RXD pins).

Broad Supply Voltage Compatibility (3.3V – 30V DC): Flexible voltage operating range makes it directly compatible with 3.3V / 5 V logic levels and 12V /24V industrial power systems.

Lockable Settings & Power-Off Memory: Retains all configured frequency and duty cycle parameters automatically upon power disconnection.

Board & Hardware Construction: Industrial-grade double-sided FR4 PCB with integrated LCD module, tactile pushbuttons, serial interface headers, and terminal blocks.

Technical Specifications:

Operating Voltage: 3.3V - 30 V DC.

Frequency Range: 1 Hz - 150 kHz (Accuracy: approx. 2%).

Duty Cycle Range: 0% - 100%.

Output Current Capacity: 5mA - 30mA.

Output Signal Amplitude: Equal to supply voltage.

Ambient Operating Temperature: -20°C - 70°C.

Usage Advice: For driving heavy DC motors or high-power loads, route the PWM signal output pin to an external power MOSFET or motor driver module.

Handling & Cleaning: Protect circuit traces against electrostatic discharge (ESD) and moisture. Clean display panel gently with a dry microfiber cloth.

Essential Industrial PWM Controller: Position as a versatile digital signal source for DC motor speed control, LED dimming, square-wave clock generation, and stepper motor driver testing.

Highlight LCD Visual Feedback & UART Serial Interface: Emphasize its crisp LCD display and remote serial communication control as key selling points over basic potentiometer-based PWM modules.

Recommended Cross-Sell Add-ons: Pair with HW-515 DC 2CH PWM Signal Generator Module, NE555 Pulse Frequency Duty Cycle Adj. Square Wave Signal Generator, AD9850 DDS Signal Generator Module, and ICL8038 Monolithic Function Signal Generator Module.
