Signal Generator PWM Board Module XY-LPWM 1Hz-150Khz 3.3V-30V مولد إشارة

XY-LPWM Signal Generator PWM Board Module 1Hz-150Khz 3.3V-30V Pulse Frequency Duty Cycle Adjustable Module with LCD Display. This compact PWM generator provides a clear LCD readout of output frequency and duty cycle, supports serial communication for external control, and saves all set parameters after power-down.

Features:
Clear LCD Display: Easy-to-read screen showing frequency and duty cycle for quick monitoring and adjustment.
Wide Frequency Range and Accuracy: Operates from 1Hz to 150KHz with range-specific accuracy of about 2%.
Serial Communication: Allows connection to other devices for remote control.
User-Friendly Design: Four independent buttons for setting frequency and duty cycle; short press changes by one unit, long press adjusts quickly. Settings are automatically saved.

Specifications:
Working voltage: 3.3-30V;
Frequency range: 1Hz-150KHz;
Frequency accuracy: about 2% per range;
Output current: approx. 5-30mA;
Output amplitude: equal to supply voltage;
Operating temperature: -20 to +70°C;
Size: 52 × 32 mm; Weight: 35 g.
Duty cycle range: 0-100%.

Frequency Display and Ranges:
The module automatically switches among four display ranges: 1–999Hz (minimum unit 1Hz); 1.00–9.99KHz (minimum unit 0.01KHz); 10.0–99.9KHz (minimum unit 0.1KHz); and 100–150KHz (minimum unit 1KHz). Examples: “100” = 100Hz; “1.01” = 1.01KHz; “54.1” = 54.1KHz; “124” = 124KHz.
